In linguistics, the aspect of a verb is a that defines the temporal flow (or lack thereof) in a given action, event, or state. As its name suggests, the habitual aspect (abbreviated ), not to be confused with iterative aspect or frequentative aspect, specifies an action as occurring habitually: the subject performs the action usually, ordinarily, or customarily. As such, the habitual aspect provides structural information on the nature of the subject referent, "John smokes" being interpretable as "John is a smoker", "Enjoh habitually gets up early in the morning" as "Enjoh is an early bird". 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.
Östen 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.
Hindi verbs#Copulas & Subaspects
Modern Hindustani (Hindi and Urdu) has a specific participle form to mark the habitual aspect. Habitual aspect in Hindi grammar is marked by the habitual participle. The habitual participle is constructed from the infinitive form of the verb by removing the infinitive marker -nā from the verb root and adding -tā. The participles agree with the gender and the number of the subject of the sentence which is marked by the vowel the participles end in. Periphrastic Hindustani verb forms consist of two elements. The first element is the aspect marker. The second element is the tense-mood marker.
There are four different copulas with which the habitual participle can be used: honā (to be, to happen), rêhnā (to stay, to remain), jānā (to go), and ānā (to come). These verbs, even when they are used as copula, themselves can be turned into aspectual participles and can be used with the default auxiliary verb honā (to be), hence forming sub-aspects that combine the nuance of two aspects.
