Sure, I can help you understand the concept of tense in English. Tense refers to when something is happening or has happened in the past, present, or future. In English, there are three tenses: past, present, and future. Past tense is used to describe events that have already happened, while present tense is used to describe ongoing events, and future tense describes events that will happen in the future.
