Present Perfect Tense.
The present perfect tense in Hindi is formed by using the auxiliary verb "हैं" (haiṅ) for plural subjects or "है" (hai) for singular subjects, followed by the past participle form of the main verb. Here is the general structure:
Singular Subject: [Subject] + [है] + [Past Participle Verb]
Plural Subject: [Subject] + [हैं] + [Past Participle Verb]
For example:
- I have eaten. - मैंने खाया है। (Maine khāyā hai)
- He has finished his work. - उसने अपना काम पूरा किया है। (Usne apnā kām pūrā kiyā hai)
- They have arrived. - वे पहुंच चुके हैं। (Ve pahunch chuke haiṅ)
