Tense, directedness and verb stem types

Greenlandic verb stems can be classified along a number of dimensions; for example according to their voice (i.e. active, passive), semantic valency (the number of logical roles in the verbal action), and aspect (how the action is viewed relative to the present).

Another group of classifications relate to the tense of a verb. Greenlandic verbal bases can generally be read as either past or present without any special marking, whereas future tense requires the addition of an affix such as V{ssa}V. This is in contrast to English, which groups the present and future together, but requires a special marking (inflection) of the verb to denote past or perfect tense. Consider the following example:

Present and future use the same form of the verb (goes), but past has a special form (went). Compare this with Greenlandic:

Here, past and present have the same form (illoqarfimmukarpoq), but the future requires adding an affix, here V{ssa}V. However, the issue of tense in Greenlandic is more complicated than this. In particular, some verb stems are inherently perfect(ive) in meaning, e.g. ilikkarpaa, 'he has learnt it', and in order to make such a verb describe a present event (e.g. 'he learns it'), an affix such as V{-liq}V is required. Thus, part of the purpose of any dictionary of Kalaallisut must be to describe the tense inherent in verbal stems, and how various affixes can alter it.

Tense and verb stem types

According to Bjørnum [7], a key factor determining the inherent tense in verb stems, is whether the stem describes a state of being or a transition. This difference is important, because states of being can be either past or present, whereas transitions are always past (unless they are modified with an affix, that moves the action forward in time). This classification is further elaborated by Nielsen [8], who divides verb stems into three classes:

Telicity

Telicity is a Grammaric term, which, according to Nielsen [8], denotes whether a verbal action is directed at a specific goal. Atelic verbs are undirected, and telic verbs are directed. This distinction is closely related to the tense and types described above. Nielsen classifies the verb stem types along the atelic/telic distinction as follows:
