TLAĪ to drink a beverage / beber poleadas, cacao, pinolli, purga o cosa semejante (M), desayuna, toma atole en la mañana (T) [(3)Tp.239, (2)Zp.19,123]. M gives an independent entry for this as an intransitive verb, implying that the nonspecific object prefix TLA- has been fused with the stem. See the verb Ī.
