What is "habitual aspect"

n. (context grammar English) A feature of the verb which specifies an action as occurring habitually, usually, ordinarily, or customarily

In linguistics, the aspect of a verb is a grammatical category that defines the temporal flow (or lack thereof) in a given action, event, or state. As its name suggests, the habitual aspect specifies an action as occurring habitually: the subject performs the action usually, ordinarily, or customarily. The habitual aspect is a type of imperfective aspect, which does not depict an event as a single entity viewed only as a whole but instead specifies something about its internal temporal structure.

Dahl found that the habitual past, the most common tense context for the habitual, occurred in only seven of 60 languages sampled, including English. Especially in Turkic languages such as Azerbaijani and Turkish, he found that the habitual can occur in combination with the predictive mood.
