A tense is a way to describe when an action or state happens in time. It's like putting a clock on a sentence.
We use tenses all the time when talking about past, present, and future events. For example, "I went to school yesterday" uses the past tense because it happened before now. If you say "I am going to school today", that's the present tense, describing something happening right now. Saying "I will go to school tomorrow" is the future tense, talking about what's still to come. We also use tenses when giving orders or making promises: "Don't eat this" (present), "You were supposed to finish your homework" (past), and "Please don't forget to water my plants" (future).
(grammar) Any of the forms of a verb which distinguish when an action or state of being occurs or exists.
