In grammar, the word tense refers to the time period in which the verb of a sentence places an action.
There are two tenses in English: present and past. Unlike many languages, English does not have a future tense. To talk about the future, English requires either the modal verb WILL or the present progressive. Learn how to talk about the future in the lesson future constructions in English.
For each grammatical tense, there are subcategories called aspects. Aspect refers to the duration of an event within a particular tense. In other words, the aspect of a tense allows us to describe or understand how an event unfolds over time. English has four aspects: simple, progressive, perfect, and perfect progressive.
