 note = {Among the several reasons why Maya glyphs have not yet been
deciphered is that the spoken language of the Classic Period (A.D.
292-909) is not well known. However, it is assumed to be close to
the Yucatec group and/or the Chol group languages, since Maya
inscriptions occur in the area where these are spoken.
This paper discusses the language recorded in the inscriptions,
using graphical and linguistical data. I analyze first some glyphs
containing graphemes T25 and T528 and then the homonymous word
kab (earth and honey), which appears in Yucatecan and Cholan
languages. The following results were obtained: (1) the syllabic
graphemes T25 (ka) and T528 (ku) have not changed into ea and cu,
as they have in Cholan languages; (2) the form kab (earth) and cab
(honey) in Chontal, Manche, and Acalan could not be explained if
the Maya glyphs recorded Cholan languages. Consequently, Maya
writing of the Classic Period is closest to the Yucatecan languages.},
