If the verb "To Drink" is "Kunywa", then should this sentence read "Baba ananywa bia kila jioni" ?
Single syllable words (i.e. kula, kuja, kunywa) keep ku- in most tenses. The exception that comes to mind is the -ja tense, which sort of means not yet.
Since this is the habitual tense, isn't this supposed to be "baba hunywa bia kila jioni"?
