Abstract
The most salient and discussed features of agrammatism are the omission and substitution of grammatical morphemes, whether bound or free, in speech production. Cross-linguistic studies have shown that language-specific features determine the pattern of omissions and substitutions found; morphological markers are almost never omitted if the resulting form is a non-word; substitutions are mis-selections from existing paradigms. In the present paper we investigate the ways in which agrammatism is manifested in Algerian Arabic, a Semitic language where simple (Ø-prefixed and Ø-suffixed) words are described as consisting of three morphemes: the discontinuous consonantal root, the discontinuous vocalic base and a CV template or skeleton (McCarthy 1975). Our findings are comparable to those previously reported, in that the three agrammatic subjects who participated in this study do omit and substitute free-standing and bound grammatical markers, and never produce non-words. More specifically, their performance is characterized by omissions of linear bound morphemes in prefixed and suffixed words, as well as substitutions of morphologically complex forms by simpler and more frequent ones. An interpretation of the subjects' performance in the light of current linguistic and psycholinguistic theories on the lexicon is proposed.
