This study is an attempt to clarify the syntactic structures of onomatopoeia and mimetic verbs. In this article, we examine the classification of derived intransitive verbs with suffix ‘-geoli-’ based on the case frame and the noun types of arguments in an inductive way. As a result, two implications can be gained through inductive considerations; The first is that we can summarize at least five subtypes of derived intransitive verbs with suffix ‘-geoli-’. The second is that the syntactic structure of the derived intransitive verbs with suffix ‘-geoli-’ is related to the meaning of the verbs. derived intransitive verbs with suffix ‘-geoli-’ are divided into two cases; one is that the subject argument of a verb is [person]/[animal] nouns and the other is that the subject argument of a verb is [body] nouns. If the subject argument of a verb is [person]/[animal] nouns, the verb can be classified as 1) the type that it is possible to have ‘to [person]’, ‘quotative clause’, or ‘[matter] nouns as object’, 2) the type that it is possible to have ‘nouns other than [matter] nouns as object’, 3) the type that it is possible to have ‘in/at [place].’ This study is meaningful to determine the scope and the object of onomatopoeia and mimetic words with characteristics of predication or ergativity.
