The early lexical development was examined with 1138 Korean infants between 18 and 36 months of age. The results show that Korean infants had 100 words around 20~21 months. The vocabulary spurt was observed between 23 and 24 months. Also they had two times more nouns than predicates(verbs and adjectives). The proportion of grammatical function words was increased with vocabulary size. However the acquisition order of function words which represent location was somewhat different from that of English and Italian.
