교체의 대상과 조건에 대하여

Abstract

This paper aims at arguing that conditions of alternation of grammatical units are restricted to phonological conditions and lexical conditions. Not only morphemes are alternated but also syntactic units are alternated. We can say about irregular verbs only if we admit that verbs are alternated under some conditions. There are lots of conditions by which morphemes are alternated. Some scholars suggest there are Phonological conditions, lexical conditions, syntactic conditions, semantic conditions, pragmatic conditions, stylistic conditions. But we don't need semantic conditions, pragmatic conditions, and stylistic conditions, as long as we admit that languages consist of meaning and sound. Meaning is not a condition but a part of a morpheme or a grammatical unit. Strictly speaking, phonological conditions are phonological conditions of grammatical units. Therefore we can suggest semantical conditions of grammatical units. And lexical conditions of grammatical units are needed when neither phonological conditions nor semantical conditions are not concerned.
