Several lists of Aztec words compared with those of various Indo-European languages have been given by philologists. The present is larger than any I have met with; several words in it are taken from Buschmann’s work on the Mexican languages. It is desirable in a philological point of view that comparative lists of words of this kind should be made, even when, as in the present instance, they are not of sufficient extent to found any theory upon. As the Aztec alphabet does not contain nearly all the Sanscrit consonants, many of them must be compared with the nearest Aztec sounds, as: SANSCRIT, t, th, d, dh, &c. AZTEC, t. SANSCRIT, k, kh, g, gh, &c. AZTEC c. q. SANSCRIT, l, r. AZTEC, l. SANSCRIT, b, bh, v. AZTEC, v. or u. The Aztec c is soft (as s) before e and i, hard (as k) before a, o, u. The Aztec ch as in _cheese_. I have followed Molina’s orthography in writing such words as _uel_ or _vel_ (English, _well_) instead of the more modern, but I think less correct way, _huel_. 1. a-, _negative prefix_ (_as_ qualli, _good_; aqualli, _bad_).
