====Tense====
Tense in Cheyenne is expressed by the addition of a specific tense morpheme between the pronominal prefix and the verb stem.  Verbs do not always contain tense information, and an unmarked present tense verb can be used to express both past and "recent" present tense in conversation.  Thus, {{Lang|chy|návóómo}} could mean both 'I see him' and 'I saw him' depending on the context.{{sfn|Leman|2011|p=191}}

Far past tense is expressed by the morpheme {{IPA|/-h-/}}, which changes to {{IPA|/-x-/}}, {{IPA|/-s-/}}, {{IPA|/-š-/}} or {{IPA|/-'-/}} before the -h, -t, -k and a vowel, respectively.  Thus:

*{{Lang|chy|návóómo}} {{gloss|I see him}}
*{{Lang|chy|náhvóómo}} {{gloss|I saw him}}

Similarly, the future tense is expressed by the morpheme {{IPA|/-hte/}}, which changes to {{Lang|chy|-htse}} after the {{Lang|chy|ná-}} pronominal, {{Lang|chy|-stse}} after {{Lang|chy|ne-}} and {{Lang|chy|-tse}} in the third-person, with the third-person prefix dropped altogether.{{sfn|Leman|2011|p=191}}
