There is no real substantive verb in the language, and adjectives, when becoming verbified, are turned into attributive verbs, as in Creek: wánti _strong, hard_; tsawántus _I am strong_; wántus _he, it is strong, hard_; wántatik _not strong_; wántigus _he is very strong_; wántatis he is not strong; wanta'hlátis _he is not strong at all_.
