Resumen de Aspect, mood and tense inflection in Dene Suliné
Verbs in the Athabaskan language Dene Suliné are obligatorily marked for aspect and mood, although aspects and some moods are never expressed independently of each other. This distribution, as well as the modal connotations of the imperfective and perfective, is best explained by positing cumulative expression of aspect and mood grammemes with some combinatorial restrictions. Tense is not obligatory, but Dene Suliné has a quasi-inflectional tense category, whose values are expressed by postverbal particles, and which interacts differently with aspect and mood categories.
Tense particle sequences and verb-particle constructions further broaden the range of possible meanings in the Dene Suliné TAM system.
