There are three main types of tenses in modern grammar: past, present, and future.
Each tense describes the time in which an action or state occurs.
The past tense refers to actions or states that happened in the past. For example: "I walked to the store yesterday."
The present tense refers to actions or states that are happening now. For example: "I am walking to the store now."
The future tense refers to actions or states that will happen in the future. For example: "I will walk to the store tomorrow."
While these are the three main tenses, many languages, including English, have additional forms that express more specific nuances of time. For example, the present perfect tense in English is used to describe actions that started in the past and continue into the present.
The past perfect tense is used to describe actions that happened before another action in the past.
There are also future perfect and future continuous tenses, which add more specific details to the future tense.
