Tense as an inflectional notion refers to marking a verbal element (a lexical verb or an auxiliary) with a morpheme that indicates the time of the event, action or state expressed by the predicate by placing it with respect to the speech time. Main tenses are past, present and future. A past event is interpreted to have happened before the speech time, a present event overlapping with the speech time and a future event after the speech time.
TÄ°D does not have a productive tense marker that appears as an inflectional morpheme on a verb. However, time lines are used to indicate the time of the event or the state.
