Frances Karttunen: 

CĒ pl: CĒMEH one / uno o una (M) The related bound form –CĒL has a long vowel, but CEM has a short one. The plural CĒMEH has the sense ‘one of several.’ As an example, C Gives cēmé tèhuāntin ‘one of us,’ cēmé azcihuà ‘one of you women’ (Cf.85v). See CEM, -CĒL. CEHCĒ redup. CĒ CĒMEH. See CĒ.
Frances Karttunen, An Analytical Dictionary of Nahuatl (Norman: University of Oklahoma Press, 1992), 26.

CEM one, entirely, wholly / enteramente, o del todo, o juntamente (M) Generally speaking, CĒ is the free form meaning ‘one’ and CEM is the corresponding bound form. In word-final position the M delabializes, yielding CEN. Within a compound the M assimilates to adjacent nonlabial consonants. Before vowels and consonants CEM retains its underlying form. In the related forms CĒ and CĒL the M is missing and the vowel is long. Z consistently has CEM where the other sources have CEM.

CEN See CEM.

Lockhart’s Nahuatl as Written: 

cē. one. also sometimes used much like the indefinite article in English. combining form cam-, cen-, or even cep-, cec-, etc. through assimilation. incorporated in a verb, entirely, forever, etc. has pl. cēmeh which usually still translates as one (of a larger group). īc cen, forever.
