TLAPĪHUIY(A) pret: TLAPĪHUIX~TLAPĪHUIYAC for something to grow, enlarge, multiply / crecer o aumentarse y multiplicarse alguna cosa (M) B attests this once and specifically marks the vowel of the second syllable short (f.9v), but it is abundantly attested in T with a long vowel, and it is also long in T’s PĪHUIC ‘something added in over and above what is paid for.’
