dokaDon't.It is possible that these forms are actually phrases, do ka and do kow because the ka and kow are singular and plural forms of “you” and the do plus either of these pronouns always carries the strong negative meaning “Don't...”. These two forms, as negative commands, always precede the verb. The do of doka or of dokow becomes phonologically attached to the pronoun. (Note also that there is no glottal stop after the do as in dò “just”, “only” which, by contrast, always follow the verb.)
