अपना (apnaa)

adjective A reflexive possessive adjective meaning 'one's own', used regardless of the subject's person, number, or gender -- it always points back to the sentence's own subject. Related to the reflexive pronoun खुद (khud).
Sense 1 : one's own (reflexive possessive)
adjective Agrees in gender/number/case with the noun it modifies, not with the subject it refers back to; the subject determines only whose 'own' it is.
Frequency: high
Cultural Note: This word forces English speakers to rethink possession in Hindi: the same sentence structure can use अपना (apnaa) or a personal possessive, but only one is grammatical depending on whether the possessor equals the subject. A useful mental habit here: whenever you're about to say 'my own', 'his own', 'their own' etc. and the possessor is the doer of the sentence's main verb, reach for अपना (apnaa) automatically, not मेरा/उसका/उनका (meraa/uskaa/unkaa).
Common Mistakes: 1) Learners often substitute मेरा (meraa), उसका (uskaa) etc. where अपना (apnaa) is required -- when the possessor is the same as the sentence's subject, Hindi grammar requires अपना (apnaa) instead of a personal possessive: राम अपनी किताब पढ़ता है (raam apnii kitaab padhtaa hai, 'Ram reads his own book') is correct; राम उसकी किताब पढ़ता है (raam uskii kitaab padhtaa hai) wrongly implies someone else's book. 2) In commands and suggestions, अपना (apnaa) is used even when the addressee is 'you', not तुम्हारा (tumhaaraa): अपना काम करो (apnaa kaam karo, 'do your own work').
