merit of his commentary to make it more abstruse and unintelligible than the text itself. It will thus be seen that the classification of words, other than பெயர் and வினை, into இடைச்சொல் and உரிச்சொல் was neither definite nor philosophical. These words have been variously classified and often in a conflicting manner by later gramınarians. For instance, the author of Pravoga-Vivekam has said that சொல்லெல்லாம் உரிச் சொல்லேயா மெனத் துணிக.
The differences between the Tamil and Sanskrit parts of speech may be briefly stated as follows:
