1 – Is Agrammatism a Unitary Phenomenon?*

Publisher Summary This chapter provides an overview of the concept of Agrammatism. In the year 1918, Deleuze was the first to provide a description of Agrammatisim, wherein it was described as a remarkable feature in the speech by certain aphasic patients. This phenomenon has recently come under the supervision of both linguists and neuropsychologists owing to the significance of it as a channel linking the linguistic construct to the brain mechanisms of language. However, the description has changed from the prior one during the modern Era, which characterizes solely as in terms of changes in the linguistic structure of speech output.
