Frances Karttunen: 

TENOCHTITLAN Tenochtitlan, the capital of the Mexica / (Tenochtitlán), en el tunal de la piedra, o nacido en la piedra (R) [(4)Bf.4r,9V,11r, (I)Rp.144]. B specifically marks the vowels of the first three syllables short. This contrasts with TENŌCHTIC 'something painted, mottled' as attested in T. NŌCH-TLI 'fruit of the prickly pear cactus' is often cited as a constituent of this name, but it contrasts in vowel length.
Frances Karttunen, An Analytical Dictionary of Nahuatl (Norman: University of Oklahoma Press, 1992), 225.

Lockhart’s Nahuatl as Written: 

full name Mēxihco Tenochtitlan. the meaning and nature of tenoch- is not entirely clear despite general consensus that it refers to a type of cactus. the rest is -t(i)-, -tlan. 233
