as "to be", "to exist", "to happen" or "to have" depending on the context, and when used in the third person it could also be translated as "there is/are". Many verbs conjugations in Hindi-Urdu are derived from participles and hence are gendered and numbered, and they agree with either the object or the subject of the sentence depending on the grammatical case of the subject of the sentence. When the subject is in the ergative or the dative case (seeː dative construction & quirky subject) the verb agrees in gender and number with the object of the sentence and with the subject when the subject is in the nominative case. Bengali Bengali is considered a zero copula language, however there are notable exceptions. In the simple present tense there is no verb connecting the subject to the predicative (the "zero verb" copula) but when the predicate expresses ideas of existence, location, or possession, for such cases the verb আছ- (ach) can be roughly translated as "to exist" or "to be present". In the past tense, the incomplete verb আছ- (ach) is always used as the copula, regardless of the nature of the predicative. For the future tense and non-finite structures, the copula is supplied by the verb হওয়া (howa), with the exceptions being the possessive and locative predicatives for which the verb থাকা (thaka, "to remain") is utilized. Bengali does not have a verb for possession (i.e. "to have", "to own"). Instead, possession in Bengali is expressed by the verb আছ- (āch) (for present and past tenses) and the verb থাকা (thaka) (for future tense) inflected with the possessed object and a genitive case for the possessor. Bengali verbs are highly inflected and are regular with only few exceptions. They consist of a stem and an ending; they are traditionally listed in Bengali dictionaries in their "verbal noun" form, which is usually formed by adding -a to the stem: for instance, করা (kôra, to do) is formed from the stem কর (kôr). The stem can end in either a vowel or a consonant. Nepali The copula verb of Nepali has two sets of conjugations. The हो (ho) set is used in sentences that equate two things, like त्यो किताब हो (tyo kitāb ho, “That is a book.”) The छ (cha) set is used in sentences that describe something, or locate where something is, like त्यो ठूलो छ (tyo ṭhūlo cha,
