Salishan languages (along with the Wakashan and the extinct Chimakuan languages) exhibit predicate/argument flexibility. All content words are able to occur as the head of the predicate (including words with typically 'noun-like' meanings that refer to entities) or in an argument (including those with 'verb-like' meanings that refer to events). Words with noun-like meanings are automatically equivalent to + NOUN when used predicatively, such as Lushootseed sbiaw which means '(is a) coyote'. Words with more verb-like meanings, when used as arguments, are equivalent to that VERBs or [VERB+er]. For example, Lushootseed ʔux̌ʷ means '(one that) goes'.
