AB - This study showed the hearing-impaired children’s longitudinal develop ment of grammar to arrange fundamental materials of their early linguistic development. The subjects of the study were two children, both of whom lived in Yeongnam area with normal-hearing parents and were diagnosed with hearing impairment before the age of two, without any additional disabilities. The utterances under natural circumstances were collected to investigate their grammatical at six-month intervals over the three years. Fourteen hundred utterances needed for the study were transcribed to analyze, by age, the developmental aspects of MLU(mean length of utterance), sentence formation, grammatical morphemes. The results of this study are as follows. First, there was a steady increase in MLUw(mean length of utterance in words) and MLUm(mean length of utterance in morphemes), showed the biggest increase in MLUm. Second, in forming simple and complex sentences, both of which were made, the use of complex sentences was increased rapidly. In order to form complex sentences, they used the simplest forms of connective endings, Some sentences contained two or more connective endings. Third, the number of used grammatical morphemes increased distinctly. Overall, the two children’s development of grammatical morphemes was a bit later or similar over hearing children’s. This study also showed that grammatical development slowed down temporarily immediately after the second surgery of a cochlear implant, which shows that hearing conditions affect language development.
