English - Tense

About

In grammar, tense is a category that locates a situation in time, to indicate when the situation takes place.

Tense is the grammaticalisation of time reference, often using three basic categories of:

  • “before now”, i.e. the past;
  • “now”, i.e. the present;
  • and “after now”, i.e. the future.

Verbs designate tense, the time when an action or state of being/condition takes place. All verbs have the characteristic of tense or the time when an action or state of being occurs.

Tense is one of the functions of a verb. Everything that happens (actions or conditions or states), happens:

  • in present time,
  • in past time,
  • or in future time.

A verb indicates the time of an action, a condition, or a state by changing its form. So, when you write and want to show when something occurs, the place to start is with the verb form you use.
