Abstract

Natural languages exhibit a great variety of verbal paradigms. For instance, in English main verbs are grammatically marked for tense, whereas in the tenseless Eskimo-Aleut language Kalaallisut they are marked for illocutionary mood. Although time is a universal dimension of the human experience and speaking is part of that experience, some languages encode discourse reference to time without any grammatical tense morphology (see e.g. Bittner 2005), or reference to speech acts without any illocutionary mood morphology.
