Umatilla Language - Morphology

Morphology

The morphological structure of Umatilla and other Sahaptin dialects is synthetic to mildly polysynthetic.
The processes used are clisis, reduplication, ablaut, compounding, suppletion, order and the most common one is affixation (suffixation in particular).
Nouns, adjectives and pronouns inflect for number and case. There are three number categories: singular, dual and plural. The singular is not marked. The dual is marked by the suffix -in (with allomorphs -win, -yn or -n depending on the final). There are two main ways to mark the plural: with the suffix -ma (tílaaki-ma 'women") and by full or partial reduplication (pšwá 'stone', pšwápšwa 'stones'). These two markers can sometimes co-exist in the same word. Several nouns feature irregular plural marks that might have been more widely used in the past, such as the prefix a- and the suffix -tu.
Verbs have the most complex morphology of all the parts of speech. Their internal structure is characterized by three major positions:

1) the pronominal prefix
This position is not necessarily occupied, it depends on the aspects of sentence structure external to the verb.

2) the theme
It can be composed of one or several elements. Theme-derivational processes include notions such as the distribution of action and the iteration of action which is expressed by the reduplication of a part of or the totality of the theme (i-ƛúp-ƛúp-ša 'he keeps on jumping up and down', where ƛúp means 'to jump'). Affixations of adverbial notions also occur: qá- 'suddenly', máy- 'in the morning, twá- 'with the edge of a long object', tísɨm- 'while sitting'.

3) the auxiliary suffix complex
Its inflectional system marks the verbs for:

• mood: indicative (unmarked), conditional and imperative
• aspect: imperfective for an action in process (suffix -ša, -šan), customary for the usual character of an action (suffix -x̣a, -x̣an)
• tense
• directionality for motion verbs: cislocative suffix -ɨm (motion or activity towards or with respect to speaker), translocative suffix -kik (motion away from the speaker).
