Synonymy from a Prototype Theory Perspective and its Symbiosis with Polysemy: Towards a New Dictionary of Synonyms

: This paper presents an attempt at providing a model for comprehensive, precise and systematic presentation of a word's synonymy within a dictionary entry, especially in the case of highly polysemous words. It is founded on the complementarity of polysemy and synonymy and a prototype-based view of the latter lexical relation. The proposed model is presented through four steps of tailoring an entry in a new dictionary of synonyms: the analysis of a word's polysemous structure, the compilation of a word's synonym sets viewed as prototype-based categories, the definition of synonyms within a set and the structure and organisation of an individual synonym set and the whole entry. Comprehensiveness of synonymy presentation according to the model is reflected in the fact that an entry lists synonym sets corresponding to different senses of the given headword as well as in the tendency for each set to offer a wide range of synonyms. Systematicity and precision in synonymy presentation are achieved primarily due to the application of prototype-based principles to the structuring and organizing of synonym sets and the defining of synonyms. The model also opens up the possibility of a transparent diagram-based visual representation of a word's synonymy in an electronic dictionary offering a more convenient visual organisation of large amounts of information.


Introduction
This paper deals with a major lexicographic challenge: how to provide dictionary users with a comprehensive and, simultaneously, precise and systematic presentation of a word's synonymy within an entry, especially in the case of highly polysemous words.In regard to this, the aim of the paper is to propose a model for tailoring an entry in a dictionary of synonyms or thesaurus, as a possible solution to the aforementioned problem of an efficient synonymy presentation.The model, intended for both an electronic and a printed dictionary with polysemous headwords having more than one synonym in, at least, two of their senses, is illustrated in the paper through its application to English.Such a dictionary can serve as a vital resource to learners of a particular language, linguists and all other users interested in linguistic research of lexical synonymy and its functioning in the given language.The model is based on the complementarity of polysemy and synonymy and a prototype-based view of the latter lexical relation.This theoretical foundation should ensure greater efficiency in providing an account of a word's synonymy as a system of mutually related synonym sets clearly displaying their members' similarities and differences.
A word has different synonyms depending on the sense in which it is used.This clearly suggests that a lexicographer intending to provide a complete picture of a word's synonymy cannot disregard the sense-specific nature of this lexical phenomenon.Hence, the proposed model promotes the symbiosis of polysemy and synonymy and its contribution to a comprehensive lexicographic account of the latter lexical relation.Moreover, various studies have pointed out that prototype theory, as a cognitive-linguistic approach, is highly beneficial for lexicographic practice (Atkins and Rundell 2008, Geeraerts 2001, Halas 2013, 2016a, 2016b, Jehle 2004, Jiang and Chen 2017, McKeown 1991, Molina 2008, Ostermann 2015, Rundell 2012, Van der Meer 2000).It has been used in both semasiological and onomasiological studies of the lexicon.In this paper, this theory is significant as the one that provides a deep insight into the internal organisation of a synonym set.

Existing lexicographic models of synonymy treatment
This subsection briefly sets forth existing models of lexicographic treatment of synonymy, which take into account the sense-specific nature of this lexical phenomenon.The overview is based on models identified in English lexicographic practice, whose products dominate the world-wide dictionary market and, more importantly, which is highly productive, diverse and innovative in terms of dictionaries of synonyms and thesauri.
There are two lexicographic models pointing out the sense-specific nature of synonymy.According to the first one, an entry contains several synonym sets, each related to a different sense of the given headword.However, such entries provide only bare lists of synonyms, lacking definitions or any explanation of their similarities or differences.Within each set, a meaning of the headword is illustrated with example sentences but it is not defined.An example of this model can be found in Collins Thesaurus: The Ultimate Wordfinder (second edition, 2002) (Figure 1) and Oxford Thesaurus of English (third edition, 2009) (Figure 2).As explained in the front matter of Oxford Thesaurus of English, the first synonym in a set is bolded and, thus, marked as the core one, which can be interpreted as a recognition of prototypicality, the notion that is significant for the model proposed in this paper, which will be elaborated on in this paper.The same model is followed in WordNet, an electronic lexical semantic database originating in the 1980s (Miller et al. 2008), which most significantly demonstrates the cooperation of polysemy and synonymy, hence it receives special attention here.Its main feature is the organisation of lexical information according to word meanings instead of word forms (Miller et al. 2008: 329).Thus, it is widely considered as closer to an online thesaurus than a dictionary.Its organisation is based on a lexical matrix in which there is mapping between a word form and a word meaning, including instances in which a word form has several different meanings (the case of polysemy) or ones in which a meaning can be realized through several different forms (the case of synonymy).
In such a mapping, polysemy and synonymy are complementary.WordNet assumes that its users are already familiar with a particular concept (meaning) and so only identifies this concept, rather than defining it.This is why meanings are represented by lists of word forms that can express them, allowing users to distinguish between different meanings.In this database, different senses of a word are represented through sets of synonyms.Hence, WordNet can be regarded in essence as a representation of polysemy which relies on synonymy.In addition to synonym sets, which are structured taxonomically so that semantic relations among them are shown, the identification of a particular meaning is also enabled by short glosses and illustrative examples.However, no meaning has a fully-developed dictionary definition.The aforementioned features of WordNet are illustrated with Figure 3: • S: (v) cut (separate with or as if with an instrument) "Cut the rope" • S: (v) reduce, cut down, cut back, trim, trim down, trim back, cut, bring down (cut down on; make a reduction in) "reduce your daily fat intake"; "The employer wants to cut back health benefits" • S: (v) swerve, sheer, curve, trend, veer, slue, slew, cut (turn sharply; change direction abruptly) "The car cut to the left at the intersection"; "The motorbike veered to the right" The second model also recognizes the sense specific nature of synonymy offering several synonym sets within an entry which correspond to different senses of a polysemous headword.Still, an entry formed according to this model provides considerably more information on synonyms comprising, primarily, their definitions accompanied by example sentences while some other pieces of information, such as additional notes on a difference between synonyms quite close in meaning, etc. can also be included However, it should be noted that this thesaurus takes only certain possible senses of a polysemous word into consideration.In addition to this, it applies greater selectivity in comparison with the aforementioned thesauri in determining synonyms for inclusion in a set to meet the needs of its target group (Lea 2008: 546).In summary, both models recognize the sense-specific nature of synonymy.However, the first one typically provides a longer list of synonyms within a set but scarce information on them (only example sentences as indicators of meaning and register/regional labels), while the second one applies greater selectivity in compiling lists of synonyms, it also provides more detailed information on synonymy within entries.It should be noted, though, that these are print dictionaries where one of the main reasons for the constraints in their models is that of space, which makes it really difficult to provide an exhaustive list of synonyms and clearly and neatly present complete information on each synonym.This constraint is, in some cases, addressed by online thesauri which are linked to dictionaries, which makes it possible to provide a list of synonyms and link them to the relevant senses of their dictionary entries (offering definitions, grammatical information, example sentences, etc.).Still, the question that remains is whether it is possible to merge the two models within a single dictionary, i.e. a dictionary of synonyms, and provide users with an inventory of a word's synonyms which is exhaustive in terms of the number of synonyms included as well as the information on each of them presented in a systematic, neat and clear way.

Synonymy from a prototype theory perspective
A general definition of synonymy frequently referenced in linguistic literature is that formulated by Cruse (2002: 486), in which it is understood as the 'similarity or identity of meaning between senses associated with two (or more) different lexical forms.' Šarić (2011: 305) points out that a cognitive linguistic theoretical framework quite suitably answers various questions related to synonymy.A number of existing cognitive linguistic interpretations of synonymy also rely on the principles of prototype theory.
The key term in a prototype-based examination of synonymy is a synonym set (e.g.big, huge, enormous), dominated by a neutral member or a semantic dominant (Dragićević 2007: 258), the prototype, more general than the other members of the given set.It functions as the basis for the other members' sense definitions (e.g.huge as 'extremely big') acting as the semantic base of the given set, representing the central semantic component common to all its members.For example, in the synonym set cut, chop, slice, carve, dice, the prototype is the verb cut since its meaning is the most neutral and general ('to divide something into two or more pieces using a sharp tool').It represents the semantic base for the other members that express more specific meanings.These distinct meanings are, in the given example, determined by a specific referent or a specific http://lexikos.journals.ac.za; https://doi.org/10.5788/33-1-1773(Article) manner of cutting (e.g.carve 'divide a large piece of cooked meat into smaller pieces', slice 'divide something into slices ', etc.).
When applied to a study of synonymy, the main postulates of prototype theory, summarized by Geeraerts (1989) as the four prototypicality effects, provide deeper insight into the internal organisation of a synonym set.The first effect is related to degrees of typicality.The position of synonyms in a set depends on their similarity to the prototype.The distance between a particular synonym and the prototype is inversely proportional to their similarity.Hence, the cline from centre to periphery is the central organisational principle of a synonym set.
The second prototypicality effect refers to the flexible boundaries of prototypical categories.Certain peripheral members might be so loosely related to the prototype that they are treated as boundary cases that can belong to another set as well.For example, in the synonym set cut, reduce, decrease, slash, lessen, diminish, lower, retrench, the last member has a rather specific meaning ('(of a business, government, etc.) make costs smaller') in comparison with the prototype ('reduce the amount/quantity of something').As the periphery of the set, it represents a boundary case that can be justifiably treated as a member of another set: retrench, economize, cut back, budget, save.Such examples indicate that synonym sets are prototypical categories whose edges are blurred rather than rigid or clear-cut.This also implies that synonym sets can be extended by new members at any point.Following Geeraert's third prototypicality effect, each member of the synonym set needs to possess only some of the prototypical features.No single set of features is necessarily shared by all the synonyms in a set, as evident in this one : cut, clip, trim, snip, shear, crop, barber, bob, pare, prune, pollard, mow.The prototypical features of this set are contained in the definition of its dominant member cut 'make something shorter with a sharp tool.'In the definition of the peripheral member mow ('make grass shorter using a machine'), the target is precisely specified ('grass'), while 'with a sharp tool' replaced by 'using a machine'.Mow shares some but not all the features with the prototype.As a prototypical category, a synonym set acts as a cluster of such partially related descriptions.
The fourth effect entails that synonym sets exhibit family resemblance.Organised around the same prototype, synonyms in a set are mutually related, sharing some sense components and overlapping to a certain extent.

The complementarity of polysemy and synonymy
Cruse's definition of synonymy claims that it is a relation between senses of different words and not words themselves.From this perspective, an in-depth study of synonymy needs to rely on polysemy, defined by Evans (2005: 33) as a phenomenon in which 'a single linguistic form' has various but mutually related senses.A more precise and thorough account of synonymy between two lexemes requires an analysis of their polysemous structures and the identification of their synonymous senses.Rasulić (2016: 129) observes that synonymy between two lexemes is primarily based on the sameness of their primary (prototypical) senses, while it is additionally reinforced by the sameness of their secondary senses.For instance, the verbs cool and chill are synonymous in their primary sense 'to make somebody or something become colder' but not in some secondary senses, such as chill 'to frighten somebody' or cool 'become calmer.'In contrast, the adjectives close and near are synonymous in their primary sense 'a short distance or time away' (e.g.Her house is close to/near the hospital.)and in their secondary sense 'near or close in family relationship' (e.g.Even their close/ near relatives didn't know about the engagement.).This clear synergy between polysemy and synonymy implies that a thorough and detailed examination of a single word's synonymy fundamentally requires an analysis of its polysemous structure, followed by a search for synonyms corresponding to different senses of the given word.Dirven and Verspoor (2004: 44) support this idea, claiming that a systematic combination of the semasiological and onomasiological approach contributes to 'a fully integrated conception of lexicology.'

The proposed model for tailoring an entry in a dictionary of synonyms
This paper presents a model as a possible solution to the aforementioned issue of comprehensive and, simultaneously, systematic and clear presentation of a polysemous word's synonymy.For the purpose of the illustration of its functioning, the model is, in this paper, applied to the case of the English verb cut.
The model starts from two fundamental theoretical principles: (1) the symbiosis of polysemy and synonymy, (2) a prototype-based view of synonymy.
The essential idea of the proposed model is that a lexicographer must first analyse the word's polysemous structure and compile an exhaustive inventory of its senses.This inventory will then serve as the structural and organisational basis for an entry, representing a system of synonym sets related to different senses of the given word.An important issue in the analysis of a word's semantic structure is sense differentiation, which might refer to either the splitting of identified senses into a larger number of more specific senses or the lumping of identified senses into a smaller number of more general senses.Which sense differentiation strategy is applied is of crucial significance for the creation of synonym sets since it directly influences their scope.Namely, depending on the applied sense differentiation strategy (lumping or splitting), a particular use of a word can be more or less specifically demarcated.The more specifically a particular sense is demarcated, the narrower the range of its synonyms is.For instance, one of the uses of the verb cut is 'reduce the amount or quantity of something,' which can be treated as a superordinate sense that http://lexikos.journals.ac.za; https://doi.org/10.5788/33-1-1773(Article) subsumes two more specific senses; 'reduce the amount of money, especially costs, prices, etc.' and 'reduce the number of people in an organisation.'In each of these three senses, the verb cut has a different synonym set: 'reduce the amount or quantity of something:' cut, reduce, decrease, slash, lessen, diminish, lower; 'reduce the amount of money, especially costs, prices, etc.:' cut, retrench, mark down, discount; 'reduce the number of people in an organisation:' cut, slim down, downsize.If the strategy of lumping is used, the two more specific senses will not be so finely differentiated but instead will be subsumed under the more general, superordinate sense.This will clearly affect the range of synonyms for this use of the verb cut since the grouping of these senses leads to the merging of three potentially narrower synonym sets into a single, wider one: cut, reduce, decrease, slash, lessen, diminish, lower, retrench, mark down, discount, slim down, downsize.The proposed model is based on the assumption that a dictionary of synonyms should provide more complex synonym sets addressing and clearly outlining the similarities and, more importantly, the differences between synonyms within an extensive range.Hence, the practice promoted in this paper employs the strategy of lumping.
The aforementioned analysis is a necessary prerequisite for the second step in the given process -compiling synonym sets for the given word. 1 The formation of a synonym set starts with the establishment of its prototype, relative to which all its other members are identified and organised.Each prototype holds the most neutral and general meaning in each set, central and common to all other set members.These members are selected as words that express the same or a more specific meaning in comparison with the prototype.They generally represent a specialisation of the basic, general, prototypical meaning, as in the following example of the set corresponding to one of the senses of the headword cut: cut, slit, slash, lacerate, gash, nick, notch.However, it might happen that the given headword is not the prototype in each of its synonym sets.For example, cut is not the prototype in the synonym set corresponding to its sense 'hurt someone's feelings'.The prototypical member carrying the meaning central to all other members is hurt, while cut is one of the peripheral members (being more restricted in its use since its typical subjects are words or actions, not people and it is typically used with an adverbial modifier, such as 'deeply').Still, the given set is listed within the entry for cut, but without any information on the synonyms (e.g.definitions, illustrative examples, etc.).Instead, cross referencing is applied, as can be seen in the illustration of the model in Section 4. Namely, the sense is cross-referenced, linking the primary entry to the entry for hurt and the given synonym set to which cut belongs and where the full information on all members of this set is provided.Hence, within an entry, complete information on synonyms is provided only in the case of sets whose central member is the headword itself.Furthermore, the overlapping of synonym sets across different entries is avoided through such a practice since polysemous headwords appear in only one completely evolved synonym set in each of their senses.It should also be noted that certain entries may contain only cross-references if their headword is not the prototype in any of its synonym sets.For example, the verb slash has two senses.The first, 'violently make a long opening or wound in something with a sharp tool,' places it as a member of the synonym set formed for sense 1 in the entry for cut, as shown in the illustration of the model in Section 4. The second, 'make something significantly smaller in quantity, amount, size, etc.' makes it a member of the synonym set corresponding to sense 3.a. in the entry for cut as well (see Section 4).The entry for slash would, thus, contain two cross references, as can be seen in the following illustration:

3.a. REDUCE THE AMOUNT OF SOMETHING
cut, reduce, decrease, slash, lessen, diminish, lower, retrench, mark down, discount, slim down, downsize However, if a headword is a member in the set whose prototype does not have more than one synonym in, at least, two of its senses, this set cannot be included into the given dictionary since it does not adhere to the principle of the dictionary's compilation stated in the introduction to the paper.
The third step refers to the defining of synonyms included into an entry.The definition of the prototype serves as the basis for formulating the definitions of its synonyms.As Pisárčiková and Benko (1996: 691) underline, the explanation of the prototypical meaning is to be general enough to encompass the essential meaning of all synonyms in a set.Furthermore, a prototype definition used as a common pattern for defining all synonyms in a set acts as a formal indication of their relatedness to the prototype and, simultaneously, their mutual connection.For example, a sense of the verb cut, for which a rather complex synonym set can be compiled, is defined as 'make an opening or a wound in something with a sharp tool or object.'Acting as a prototypical definition, it serves as the base for all other synonym definitions in the set.Their specific sense components are tacked on to the prototypical definition, so their specific variations of its meaning are demonstrated.In this way, within a set, differences in meaning between any particular synonym and the prototype, as well as between synonyms themselves, is made apparent.As Adamska-Sałaciak (2013: 330) emphasizes, when choosing between alternative synonyms, it is not only their similarities but also their differences that play an important role.Thus, in the definition of the synonym slit, 'an opening or a wound' is more precisely and specifically determined by adding the adjectives 'long and narrow' to the basic, prototype pattern.The final formulation of this slit is 'make a long and narrow opening or wound in something with a sharp tool or object.'Similarly, in the case of the synonym slash, the way in which an opening or a wound in something is made is specified with the adverb 'violently,' while the opening or wound itself is described as 'long.'This yields the final formulation; 'violently make a long opening or wound in something with a sharp tool or object.'In the definition of the synonym lacerate, the added information refers to the fact that there are typically a number of openings or wounds as well as the object in which they are made ('make a number of openings or wounds in skin or flesh with a sharp tool or object').
Definitions can also include stylistic and pragmatic information on synonyms since the contrast among them is often reflected in their specific collocational range or associative meaning.This can include expressive features (e.g.approving, disapproving) or stylistic features related to a specific dialect (e.g.British, American, etc.), sociolect (e.g.standard, non-standard, slang, etc.), register (e.g.formal, informal, spoken, written) or field (e.g.geometry, law, computing, etc.).These pieces of information can be provided in the form of labels before the very text of definitions.Typical collocations of a particular synonym that distinguish it from other synonyms in the given set are highlighted in example sentences following the definition.In addition, typical referents used with a particular synonym are provided in brackets before its definition (e.g.retrench '(of a business, government, etc.) make costs smaller').
The fourth step deals with the structure and organisation of each individual synonym set as well as each entry as a whole.An entry represents a system of a headword's synonym sets.Since each synonym set in this system is related to a particular sense of the headword, these sets are arranged so that their mutual relations correspond to appropriate senses in the polysemous structure of the headword.In other words, synonym sets are mapped according to, and following, the organisation of their corresponding senses in a particular polysemous structure.Therefore, sets corresponding to closely related senses are grouped within the same numbered section.Every set within a section is positioned within its specific field.The first set in a section is the one corresponding to the most general sense in the given group.This set regarded as the superordinate one is followed by sets corresponding to more specific senses, probably derived from the most general one through metaphorical extension, specialization or any other semantic mechanism.These subsets are numbered according to the model 1.a, 1.b, 1.c, 2.a, 2.b, etc. and ordered according to the descending scale of their corresponding senses' frequency of use in the contemporary language. 2 The internal structure and organisation at the field level in an entry or an individual synonym set itself follow the principle 'from centre to periphery.'The prototype is followed by other members ordered according to the declining scale of their similarity to it.For example, in the synonym set of the headword cut corresponding to the sense 'reduce the amount or quantity of something,' members positioned immediately after the prototype are reduce and decrease, since they show relatively close similarity to it.These two synonyms are followed by slash, whose meaning is slightly more specific in comparison with the prototype, as the extent to which something is reduced is implied ('significantly').Slim down and downsize are the most peripheral members of the set on account of the precise specification of the referent ('companies, organisations') and their respective, specific components of manner ('by reducing the number of jobs') and aim ('in order to reduce costs').If two or more synonyms are equally similar to the prototype (for example, reduce and decrease in the given set), their placement in the set is also determined according to the declining scale of their frequency of use in the contemporary language.The gradient relatedness of synonyms to the prototype is also visually presented in the sample entry in Section 4 by the indentation of their definitions; the greater the indentation the weaker the synonym's similarity to the prototype.If two synonyms are equally similar to the prototype, their indentation is the same.Synonyms practically identical to the prototype are not indented.

evident in such an entry as the one presented in the previous section of the paper.This entry can be displayed in the same visual layout in a print dictionary and an electronic dictionary.The only exception is cross referencing to another entry in the case of synonym sets in which the headword is not the prototype (e.g.See the entry for hurt verb).This note is omitted in an electronic dictionary as unnecessary since, even in the aforementioned case, the information on all synonyms can be accessed from the given headword's entry through hyperlinking, the additional benefit possessed by this format.Hyperlinking enables a visual representation that, in its basic form, offers a smaller amount of initial information, yet provides simple access to more detailed information.This initial presentation can be limited to only sense definitions of the given headword and synonym sets corresponding to them yet each synonym in these sets can be hyperlinked to more complete information.This can include its definition, example sentences, pronunciation, grammatical patterns in which it appears, and more.In this way, the basic appearance of an entry is not burdened with a large amount of detailed information, enabling a simpler and more efficient search experience.Hyperlinking is especially convenient for cross-referencing, a practice frequently used by the proposed model and already discussed in Section 4 of the paper.Moreover, as the proposed model is based on the symbiosis of polysemy and synonymy according to the principles of prototype theory, an electronic environment allows for the visual representation of an entry in the form of a diagram, such as the following one: The diagram has already been recognised in lexicographic practice as suitable for presenting semantic structures of words and lexical relations, as in The Thinkmap Visual Thesaurus or Visuwords, an online graphical dictionary.The diagram above is based on the prototype theory view of a polysemous struc-ture as a hierarchically organised set of derivationally related senses gathered around their prototype 4 .This representation of a word's synonymy includes only a part of its corresponding polysemous structure; only those senses for which synonym sets can be formed.Each of the ellipses in the diagram for the verb cut establishes both one of its meanings and the corresponding synonym set, whose internal organisation is prototype-based.In each case, the prototype is in the centre of the area enclosed by an ellipse, while its synonyms are represented by points on the given closed curve.The position of a synonym depends on its similarity with the prototype -the shorter the distance between a point on an ellipse and its centre (shown by the line connecting them), the greater the similarity between the given synonym and the prototype, and vice versa.Synonyms that are equally similar to their prototype are symmetrically positioned on a curve in relation to the centre (e.g.cut and tape-record in the ellipse presenting the sense 'make a sound recording').In an electronic dictionary, each synonym on an ellipse would be hyperlinked to the complete information on it, including all elements contained in the sample entry shown in Section 4. All pieces of information contained in the textual entry can thereby also be provided through a diagram.Such a diagram-based entry might offer its users a clearer and more succinct representation of a word's integrated synonymy.Furthermore, this visual format enables a quick and easy search for the desired word, including all the necessary information on semantic contrasts among synonyms.

Conclusion
Compared to existing ones, this model functions as an attempt to unify such synonym lists as found in Collins Thesaurus: The Ultimate Wordfinder or the Oxford Thesaurus of English with information on such synonyms as offered in the Oxford Learner's Thesaurus.Providing users with as much relevant information as possible about a word's synonyms within one entry is the driving concept behind this model.In fulfilling this goal, the model cannot follow the selective approach employed by the Oxford Learner's Thesaurus, but rather embraces one of inclusiveness.
The proposed model achieves comprehensiveness due to its relying on synonymy's dependence on polysemy, as one of its fundamental principles.It provides synonym sets related to different senses of the given word.The model is inclined towards inclusiveness within an individual synonym set as well, which can be, thus, complex including a wide range of synonyms.
Such an approach to a word's synonymy requires a long and complex dictionary entry providing a vast amount of information, which, however, needs to be clearly presented to dictionary users.The principle of complementarity between polysemy and synonymy also contributes to systematicity in the organization of synonym sets within an entry, which follows the organization of appropriate senses in the given polysemous structure.Hence, there are sec-tions including sets corresponding to closely related senses.This model demonstrates that a word, beyond its polysemous structure, can acquire an organised structure encompassing all its synonyms.Such organization of synonym sets accompanied by indicators of corresponding word meanings is expected to enable an easier and quicker search for the needed set and, simultaneously, individual synonym.
Further systematicity and consistency in synonymy presentation is achieved by the application of the prototype-based view of synonymy.In each synonym set, all its members are identified and organised relative to the prototype according to a declining scale of their similarity to it, which can also be visually represented in an entry.The organisation of synonyms in a set obviously follows a clearly established system.In addition to this, there is a set pattern in defining synonyms according to which the definition of the prototype serves as the base for definitions of all other synonyms in the set.The applied prototypebased strategies can help users easily understand similarities and differences in meaning between any particular synonym and the prototype, as well as between synonyms themselves.Due to efficient demonstrating of nuances in meaning, it is believed that users can quickly identify synonyms that most accurately and precisely express the meanings sought.The application of prototype-based principles also affords a transparent diagram-based visual representation of a word's synonymy in an electronic dictionary offering a more convenient visual organisation of large amounts of information.
The cooperation of polysemy and synonymy, as a principle, is common to the proposed model and WordNet.However, in this model, based on a lexicographic treatment of synonymy that relies on polysemy, the cooperation of these two relations is viewed from a perspective opposite to that adopted by WordNet, in which polysemy depends on synonymy.It might be assumed that the lexicographic outcome would be the same regardless of which of the two perspectives is employed.Yet this is not true, despite their similarities.While in both cases the outcome is an entry containing a number of synonym sets corresponding to different senses of a polysemous word, a more detailed examination shows that synonym sets in the two models have different functions.As illustrated in Figure 3, synsets in WordNet serve to help a user to identify a particular lexical meaning.The selection of their members and their internal organisation are not meant to provide a comprehensive list of various ways of expressing a particular meaning, or to show mutual semantic distinctions among synonyms they comprise.This indicates that such sets do not fulfil the recognised primary functions of a dictionary of synonyms.In contrast, in the model proposed in this paper, synonym sets are designed precisely to serve these functions.Therefore, a synonym set corresponding to a particular meaning in WordNet will almost certainly be measurably different from one related to the same meaning in the proposed model.For example, the synset formed in WordNet for one of the senses of the verb cut, 'reduce the amount of something,' contains the following synonyms: reduce, cut down, cut back, trim, trim down, trim back, cut, bring down.The members of the synonym set formed for the same meaning according to the model proposed in this paper are the following: cut, reduce, decrease, slash, lessen, diminish, lower, retrench, mark down, discount, slim down, downsize.Clearly, the representation of polysemy relying on synonymy and the representation of synonymy relying on polysemy are two different models of cooperation between the two lexical phenomena whose differing intrinsic purposes result in markedly different lexicographic outcomes.

1.
In this paper, only the lexical segment of the lexicon is taken into account in the formation of synonym sets.Thus, these sets include only words.2.
For the purpose of illustrating the proposed model in Section 4 of the paper, the information on the frequency of particular senses of the verb cut has been obtained from English generalpurpose and learner's dictionaries listed in the References.

3.
For the purpose of forming a sample entry as an illustration of the proposed model, English thesauri listed in the References have been used as sources of possible synonyms of the verb cut.
