This thesis presents a syntactic description of spoken Tamil, based on the author's own speech. The introductory first chapter describes briefly some characteristics of Tamil and gives a note on the methodology. This is followed by a chapter which deals with the transcription used and with features of junction. The structure and system of the sentence, the clause, the nominal group, the verbal group and the adverbial group are described in the next five chapters. The last two chapters deal with the morphology of the nominals and the verbals.
