To reveal when toddlers and children acquire the grammatical morpheme of Korean language, this study investigated the way they respond to some picture tasks. The object of this research was 174 children ranging from 18 months to 60 months, who were selected from two child-care centers located in Seoul and Gyeongi Province. Following the statistical analysis of the data, this study ascertained that 2-, and 3- year-old children acquire the most part of grammatical morphemes such as nouns, pronouns, verbs, adverbs, adjectives, and interrogation terms. The fact that the process of acquisition was significantly different among six age groups has proved the hypothesis of the gradual acquisition of grammatical morpheme.
