Verbs in Yahgan are often compounded ("serialized"). Bound subject pronouns (ha- 1st, sa- 2nd, kv- 3rd), unmarked for number, are prefixed, coming before voice prefixes (such as ma(m) -passive, tu:- causative, u:- permissive, T- circumstantial (with allomorphs t-, , tu:-, ts-, chi:-, chi-, ch-), l- back, in response to, etc.). Aspect (such as progressive -gaiata-), tense (for instance -vde: simple past, -u:a simple future, with added increments -vde:aka 'further past', -u:ana 'further future), and mood (generally in that order), etc. are suffixal, along with the two 'benefactive' suffixes -a:gu: 'for self', -ya:gu: 'for another'. Number within the verb (number of subjects or acts) can be encoded by overt marking (once -ata, twice -a:pai/-pikin-, several times -a:misiu:, plural -isin-/-u:sin-, or even none -apisiu:) or the many different distinct plural verbs (for instance mvni 'sg. to stand', palana 'pl. to stand'; ata 'sg. to take, convey', tu:mi:na 'pl. to take, convey').
