What Is the Indefinite Aspect? (with Examples)

Our Story

Indefinite Aspect

The indefinite aspect (or simple aspect as it's more commonly called) is the verb form used to express a fact. Unlike other aspects (like the progressive aspect or the perfect aspect), the indefinite aspect does not make it clear whether the action is a complete action or a habitual action. For example:
  • Mount Everest is the highest mountain in the world. (fact)
  • We climbed Mount Everest yesterday.
  • (This is a fact. Context tells us it's a complete action.)
  • He climbs Mount Everest every year.
  • (This is a fact. Context tells us it's a habitual action.)
Any verb (in the past, present or future) in the simple tense is said to be in the "indefinite aspect."

The Indefinite Aspect Is Quite Complicated

Despite also being called the simple aspect, the indefinite aspect is not indefinite. A verb in the indefinite aspect relies on a combination of context and tense to clarify whether the action is complete or on going. For example:
  • She ate cake.
  • (The tense tell us this is a complete action, but it is unclear whether this was a habitual action or not. The context doesn't make it clear.)
  • She ate a cake.
  • (This is also a complete action. This time, context suggests it wasn't a habitual action.)
  • She eats cake.
  • (This time, it's unclear whether this is a habitual action or just a fact.)
With the exception of the simple future tense (which is formed with the auxiliary verb "will"), verbs in the indefinite aspect are not formed using auxiliary verbs or participles. So, it's quite easy to form.

    Why Should I Care about the Indefinite Aspect?

    Native English speakers can use all twelve tenses without giving the grammar a second thought. However, if you're learning or teaching English, you must spend time learning the tenses because expressing when something occurs is a fundamental communication skill. The simple tenses are usually the first tenses taught, but, as we've covered, they're not simple at all, and they're not used too often during a natural conversation.

    Remember that tenses do not just tell us whether something is a past, present, or future action. They also tell us whether the action is habitual, completed, or ongoing (called the aspects).

    The trick to learning tenses is mastering the following:
    • The verb "to be" in all its forms (am, is, are, was, were, will be)
    • The verb "to have" in all its forms (has, have, had, will have)
    • Present participles, i.e., the "ing" form of verbs (e.g., playing, thinking, eating)
    • Past participles (e.g., played, thought, eaten)
