processes as described above. /li/→∅ / /tʃi/ balii-li-chi-h→balii-chi-h /li/→∅ / /t/ balii-li--h→balii-t Schwa insertion Schwa insertion: when a glottal fricative or a velar stop precedes a voiced consonant within a consonant cluster, a schwa is inserted to break up the consonant cluster. ∅→ / [+voiced] consonant ∅→ / [+voiced] consonant 'ahnih'→/ahənih/ Vowel deletion Vowel deletion is the process of a short vowel being deleted at a morpheme boundary. It occurs when an affix containing a short vowel at the morpheme boundary binds to a word that also contains a short vowel at the morpheme boundary. For most vowel deletion cases, the preceding short vowel is deleted at the morpheme boundary. V→∅ / V /baliili-aatʃĩ-h/→baliilaatʃĩh If a class II suffix attaches to a word that results with two short vowels occurring together, the short vowel that follows the class II suffix is deleted. V→∅ / V /sa-ibaa-waʃoohah/→sabaa-waʃoohah Morphology and grammar Verbal morphology 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. Verbs may be preceded by up to three prefixes and followed by as many as five suffixes. In addition, verb roots may contain infixes that convey aspectual information. Verb prefixes The verbal prefixes convey information about the arguments of the verb: how many there are and their person and number features. The prefixes can be divided into three sorts: agreement markers, applicative markers, and anaphors (reflexives and reciprocals). The prefixes occur in the following order: agreement-anaphor-applicative-verb stem. Agreement affixes The agreement affixes are shown in the following chart. The only suffix among the personal agreement markers is the first-person singular class I agreement marker /-li/. Third-person is completely unmarked for class I and class II agreement arguments and never indicates number. Some authors (Ulrich 1986, Davies, 1986) refer to class I as actor or nominative, class II as patient or accusative and class III as dative. Broadwell prefers the neutral numbered labels because the actual use of the affixes is more complex. This type of morphology is generally referred to as active–stative and polypersonal agreement. Class I affixes always indicate the subject of the verb. Class II prefixes usually indicate direct object of active verbs and the subject of stative verbs. Class III prefixes indicate the indirect object of active verbs. A small set of stative psychological verbs
