schemas for the context sensitive phonological modification of base morphemes. Analyzing all the possible combinations of morphemes and phonological contexts in Tlingit and constructing a regular language to describe them is a daunting but tractable task. Despite not being a fusional language, Tlingit is still highly synthetic as an agglutinating language, and is even polysynthetic to some extent. The verb, as with all the Na-Dené languages, is characteristically incorporating. Nouns are in comparison relatively simple, with many being derived from verbs. Word order Tlingit word order is SOV when non-pronominal agent and object phrases both exist in the sentence. However, there is a strong urge to restrict the argument of the verb phrase to a single non-pronominal noun phrase, with any other phrases being extraposed from the verb phrase. If a noun phrase occurs outside of the verb phrase then it is typically represented in the verb phrase by an appropriate pronoun. Nouns See main article: Tlingit noun Pronominals Tlingit has a complex system of pronominals, which vary depending on their relationship to the verb. The subject pronominals are incorporated into the verb in its subject slot. The object pronominals are also technically incorporated into the verb (i.e. the verb "complex"), but most are graphically independent. They are divided into three classes, the verbal object, nominal object, and postpositional object. There are also the independent pronominals which are completely separate from the verb and can be used in dependent clauses or in subject or object position. The pronominals all have related semantic values, and their organization can hence easily be visualized in a table. {| class="wikitable" !rowspan=2|Type !!rowspan=2| Subject !!colspan=3| Object !!rowspan=2| Independent |- !
