Two kinds of speech symptoms observed in a jargon aphasic was reported ; “the iterative pattern of phonemic variation and semantic variation” . The former is the same as the stereotypic pattern of alliteration and assonance of neologism, which was described by Green (1969). The latter, which we described for the first time in this paper, is characterized by a series of several words which have closely semantic relations each other or belong to the same semantic category. So the iterative pattern of phonemic variation (=alliteration and assonance) is characteristic to neologistic jargon, as that of semantic variation is suggested to be characteristic to a certain type of the semantic jargon.
