Tenses are one of the most important parts of English grammar.

They help us talk about actions that happen in the present, happened in the past, or will happen in the future.

Many English learners find tenses confusing because there are twelve major tenses. The good news is that all twelve tenses follow a simple pattern.

English tenses are built from:

• Three time periods:
  • Present
  • Past
  • Future

Combined with:

• Four aspects:
  • Simple
  • Continuous
  • Perfect
  • Perfect Continuous

3 × 4 = 12 English Tenses

Once you understand this structure, mastering English tenses becomes much easier.

Why Are Tenses Important?

Tenses tell us:

• When something happens
• Whether an action is finished
• Whether an action is ongoing
• Whether an action happened before another action

Compare:

• I eat breakfast.
• I ate breakfast.
• I will eat breakfast.

The action is the same, but the time changes.

That is the purpose of tenses.
