Frances Karttunen: 

TLAŌCOY(A) pret: TLAŌCOX to be sad / estar triste (M) [(3)Bf.2r,6v, (1)Cf.121r, (3)Zp.121,125,218]. Z has an intrusive glide Y between the first two syllables in derivations from this, and so does B, although B does not indicate one in TLAŌCOY(A) itself. In derivations from this verb T has the reflex of ĀO instead of AŌ.TLAŌCOYALŌ nonact. TLAŌCOY(A).
