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.
[2]: 101 Especially in Turkic languages such as Azerbaijani and Turkish, he found[2]: 111 that the habitual can occur in combination with the predictive mood.
[3] There are four different copulas with which the habitual participle can be used:[5] honā (to be, to happen), rêhnā (to stay, to remain), jānā (to go), and ānā (to come).
This usage requires a lexical indication of when the action occurred; by itself the sentence We would go there does not express habituality, while We used to go there does even though it does not specify when.
English can also indicate habituality in a time-unspecific way, referring generically to the past, present, and future, by using the auxiliary will as in He will make that mistake all the time, won't he?.
[9] Romance languages like French, Spanish, Italian, and Portuguese do not have a grammatical form that is specific to the habitual aspect.
Cantonese, a Sinitic language, has a dedicated particle to express the habitual aspect, 開 hoi1, which follows the verb.
