Primary stress nearly always[8] occurs on the penultimate (second to last) syllable. In any case, the IPA stress symbol is always placed immediately before the stressed syllable.

The stressed vowel is pronounced with raised pitch, which is optionally indicated by an acute accent on the vowel of the stressed syllable.
Nahuatl has four possible syllable clusters CVC, CV, VC and V[9][10]
^/n/ is Nahuatl's most weakly pronounced consonant (Lockhart 2001, p. 112).
^The Nahuatl /o/ is different from every English vowel, but the nearest equivalents are the vowel of coat (for most English dialects) and the vowel of saw.
^The only exception is vocative forms, in which case the final syllable is stressed.
