In this paper we consider the adverb “chea” in Hiaki, a Uto-Aztecan language spoken in

southern Arizona and northern Mexico. “Chea” has a comparative/superlative meaning ‘more/most’,

but it also has other uses we propose to identify as ‘actually’, ‘even’, and ‘really’. We argue here

that the latter three uses are built off the comparative meaning, relying on an analogy between

degrees and truth values.
