This paper aims to tease out the paths of grammaticalization of Southern Min causative verbs, chhoa7拽, kah4甲, sai2使, kio3叫, khit4乞and thoo3度. Their semantic extensions affect the interpretation of the pivotal construction which they all share. These causative verbs, at a light verb position, link two events which have leeway for reinterpretations. Kah4甲and kio3叫 go from directive causative to stative causative. In early SM texts, sai2使 was a productive directive causative vverb and chhoa7拽 was a full-fledged stative casutive verb. Khit4乞 and thoo3度are interpreted differently in different constructional types. As verbs of giving, they develop ditransitive construction, then permissive causative and finally passive. The lexical properties of these verbs endow the causative construction with new meanings.
