पता चलना (pataa chalnaa)

verb A common conjunct expression built from पता (pataa, 'clue/trace/address') plus चलना (chalnaa, 'to move'), meaning 'to find out' or 'to come to know' -- it frames knowledge as something that arrives to you rather than something you actively acquire.
Sense 1 : to find out, come to know
verb, intransitive The knower is marked with को, and पता (pataa) agrees as the grammatical subject with चलना (chalnaa): मुझे पता चला (mujhe pataa chalaa, 'I found out'), not the person as subject.
Synonyms: जानना (jaannaa, to know, active), मालूम होना (maaloom honaa)
Frequency: high
Cultural Note: This is a classic dative-subject construction, like लगना (lagnaa) or अच्छा लगना (achchhaa lagnaa) -- Hindi treats discovering something as an event that happens *to* you, not an action you perform. You'll hear this constantly in gossip and news contexts: अभी पता चला (abhii pataa chalaa, 'I just found out') is a staple reaction line in everyday conversation.
Common Mistakes: 1) Learners try to make the person the subject as in English ('I found out') and say मैं पता चला (main pataa chalaa) -- wrong; it must be मुझे पता चला (mujhe pataa chalaa). 2) The thing found out is usually expressed as a कि-clause or with का/की, not as a direct object: उसे मेरी शादी का पता चला (use merii shaadii kaa pataa chalaa, 'he found out about my wedding'). 3) Confusing पता चलना (pataa chalnaa, the moment of discovery) with पता होना (pataa honaa, the state of already knowing) -- मुझे पता है (mujhe pataa hai, 'I know') versus मुझे पता चला (mujhe pataa chalaa, 'I found out just now').
Sample Sentences:

Sense 2 : to become known/apparent, to turn out (that...)
verb, intransitive Often used impersonally with a following कि (ki, 'that') clause, without any को-marked experiencer stated: पता चला कि वह नहीं आएगा (pataa chalaa ki vah nahiin aaegaa, 'it turned out that he wouldn't come').
Synonyms: साबित होना (saabit honaa, to be proven, when result-oriented), ज़ाहिर होना (zaahir honaa, to become evident)
Frequency: high
Cultural Note: You'll hear बाद में पता चला (baad men pataa chalaa, 'later it turned out') used to narrate plot twists in stories, gossip, or news retellings -- it's the Hindi equivalent of the dramatic reveal in a conversation.
Common Mistakes: 1) Learners sometimes add an unnecessary को-experiencer when the sentence is meant as a general, impersonal revelation of fact (like news) rather than one person's personal discovery -- both are grammatical, but the impersonal version without को reads more like 'as it turned out' or 'apparently'.
Sample Sentences:
