The category tense expresses a temporal relation between a situation, an event or action that happens at a certain point in time in reference to the utterance time. In general, three broad categories are distinguished, namely past (‘he walked’), present (‘he walks’) and future tense (‘he will walk’). This chapter deals with the morphological markers of tense in DGS and the use of time lines. Temporal adverbials indicating tense are discussed in Lexicon 3.5.2 and Syntax 6.4.2.1.
