     The most serious defects of the Lexicon are those relating to vocabulary, definition, and derivation. Hundreds of simple words and thousands of compound words are missing in the Lexicon. There is only one simple word in Tamil to denote urination, and that has not found a place in the Lexicon. M†˜, to urinate, is most common in the Tirunelveli, Madurai and Ramanathapuram Districts, and is regularly conjugated as an intransitive verb.

     Even literary words are remaining in their hundreds outside the Lexicon, for instance, †re‰uttorumo‰i, …re‰uttorumo‰i, nedu½jinai, šinaimudaŠpeyar, va––acci‹aiccol, tadumƒŠuto‰iŠpeyar, pƒava––am etc., of Tolkƒppiyam, andarakk†l, ka––e‰uttu, pa–mo‰inarambu etc., of Silappadikƒram; puguvƒyil, puŠappadu vƒyil etc., of Adiyƒrkkunallƒr's commentary; karunga˜amar, karumugamandi, sembin„ŠŠai etc., of Naccinƒrkkiniyar's commentary; illaŠa ve˜˜ai, aimpadai viruttam, sendami‰mƒlai, yƒnaitto‰il, v„ndankudaimaŒgalam etc. of Pa‹‹irupƒ——iyal; and araisumakka˜, ka–akku vƒriyam, kaliŒgu vƒriyam, kudumbu vƒriyam, s)iŠudanam,tadiva‰i vƒriyam, ti——ukkƒran, naduvirukkai, nƒdƒ˜vƒn, pa‰aniyƒyam, perundarattukkum„lnƒyagam, po‹vƒriyam, etc., of the inscriptions.

     On the contrary, numerous unnecessary foreign words have been incorporated in the Lexicon in their naturalised and foreign forms.
