tense conjugation only for the verb होना (honā) [to be] and the rest of the verbs lack this conjugation. The indicative imperfect forms of होना (honā) comes from Sanskrit स्थित (stʰita) "standing, situated" which are derived from the PIE root *steh₂- (“to stand”). The imperfect conjugation is derived from a participle form and hence its conjugations agree only with the number and gender of the grammatical person and not the pronoun itself. So, the grammatically singular pronouns (e.g., मैं ma͠i "I" and तू tū "you" etc.) are assigned the singular imperfect forms (i.e. था thā or थी thī) depending on the gender of the person or the noun they refer to, and the grammatically plural pronouns (e.g. हम ham "we" etc.) are assigned the plural imperfect forms (थे thē and थीं thīm̊). An exception to this is the pronoun तुम (tum) which takes in the plural imperfect form (थे thē) in masculine gender but singular form (थी thī) in feminine gender. These imperfect conjugations also act as copula to form the imperfect past forms for the three grammatical aspects that Hindi hasː Habitual, Perfective, and Progressive aspects.

There is only one periphrastic tense which functions as both the present progressive and present perfect with reference to the setting in which is placed. Indo-Iranian languages Persian Like all other past tenses, imperfect is conjugated regularly for all verbs. Formation: [preverb] + mi- + past stem + past ending. Conjugation of the imperfect indicative for the first person singular is shown in the table belowː Slavic languages Most Slavic languages have lost the imperfect but it is preserved in Bulgarian and Macedonian. It is also officially retained in Serbian and Croatian but is considered old-fashioned and restricted to literature for poetic and stylistic reasons. Turkish Turkish has separate tenses for past continuous and imperfect. To form the past continuous tense for Turkish verbs, after removing the infinitive suffix (-mek or -mak), take the present continuous tense suffix "-yor" without personal suffixes, and add the ending for the simple past plus the appropriate personal suffix As -du (which has a rounded back vowel) succeeds -lar (which has an unrounded back vowel), instead of -yor (which has a rounded back vowel) when the subject is the third person plural onlar, it becomes -dı (which has
