PĀC(A) vrefl.vt to bathe; to wash, launder something / se lava, se asea (T), lavar algo o batanar paños o sayales (M) In a section on the preterits of verbs represented by MACA and TOCA which retain their stem-final vowels, C points out that PAC(A) follows the rules of vowel-dropping but leaves it open that it may have an alternate preterit PĀCAC (Cf.31v). M gives alternative preterits -PĀC and -PĀCAC for TLAHTLAPĀC(A) 'to wash something repeatedly.' This verb preserves the Proto-Uto-Aztecan initial *P which has been lost in Ā-TL 'water, liquid.'PĀCALTIĀ caus. PĀC(A).PĀCALO altern. nonact. PĀC(A). PĀCŌ altern. nonact. PĀC(A).
