Choctaw verbs display a wide range of inflectional and derivational morphology.

In Choctaw, the category of verb may also include words that would be categorized as adjectives or quantifiers in English.

The verbal prefixes convey information about the arguments of the verb: how many there are and their person and number features.

Broadwell prefers the neutral numbered labels because the actual use of the affixes is more complex.

A small set of stative psychological verbs have class III subjects; an even smaller set of stative verbs dealing primarily with affect, communication and intimacy have class III direct objects.

A small set of psychological verbs have subjects with class III agreement.

[22] Negation is multiply marked, requiring that an agreement marker from the N set replace the ordinary I agreement, the verb appear in the lengthened grade (see discussion below), and that the suffix /-o(k)-/ follow the verb, with deletion of the preceding final vowel.

(I guess)There are also suffixes of illocutionary force which may indicate that the sentence is a question, an exclamation, or a command:[26] Awashlifry-tok-PT-o̱-QAwashli -tok -o̱fry -PT -Q'Did she fry it?

Some examples that show the grades follow: In this example the l-grade appears because of the suffixes /-na/ 'different subject' and /-o(k)/ 'negative': lowaburn-t-SStaahacomplete⟨LGR⟩-na-DSfalaamareturn-t-SSak-1S.N-iiya-go⟨LGR⟩o-NEG-kii-NEG-ttook-DPASTlowa -t taaha -na falaama -t ak- iiya- o -kii -ttookburn -SS complete⟨LGR⟩ -DS return -SS 1S.N- go⟨LGR⟩ -NEG -NEG -DPAST'...

Choctaw nouns can be followed by various determiner and case-marking suffixes, as in the following examples, where we see determiners such as /-ma/ 'that', /-pa/ 'this', and /-akoo/ 'contrast' and case-markers /-(y)at/ 'nominative' and /-(y)a̱/ 'accusative':[29] allachildnaknimale-m-that-at-NOMalla nakni -m -atchild male -that -NOM'that boy (nominative)'Hoshibird-at-NOMittitreechaahatall-m-that-ako̱-CNTR:ACCo̱-SUPE-biniilisit-h-TNSHoshi -at itti chaaha -m -ako̱ o̱- biniili -hbird -NOM tree tall -that -CNTR:ACC SUPE- sit -TNS'The bird is sitting on that tall tree.'
