मचना (machnaa)
verb
An intransitive verb meaning for a commotion, chaos, noise, or excitement to erupt or break out; it almost always shows up paired with a noun like शोर (shor) or हलचल (halchal) as its grammatical subject, describing the disturbance itself as the one 'happening.'
Sense
1
:
for commotion/noise/chaos to break out or erupt
verb, intransitive The subject of मचना (machnaa) is almost always an abstract noun of disturbance -- शोर (shor, noise), हंगामा (hangaamaa, uproar), हलचल (halchal, stir), खलबली (khalablii, panic/flurry), धूम (dhoom, excitement/buzz) -- rather than a person; the person affected, if mentioned, appears with में (men) or पर (par), e.g. 'शहर में हंगामा मच गया' (shahar men hangaamaa mach gayaa, 'an uproar broke out in the city').
Synonyms: छा जाना (chhaa jaanaa), फैल जाना (phail jaanaa), भड़कना (bhadaknaa)
Frequency: medium
Cultural Note: मचना (machnaa) and its transitive twin मचाना (machaanaa) are a classic intransitive/causative pair: बच्चों ने शोर मचाया (bachchon ne shor machaayaa, 'the kids made noise') versus शोर मच गया (shor mach gayaa, 'noise broke out') -- the first names the agent, the second just reports the eruption as if it happened on its own, which is a very Hindi way of describing chaos without pointing fingers.
Common Mistakes: 1) Learners try to make a person the subject of मचना (machnaa) (like 'he erupted'), but the verb's subject is the disturbance itself -- शोर मचना (shor machnaa), हंगामा मचना (hangaamaa machnaa) -- and the person only appears via में (men) or पर (par). 2) Do not confuse with मचाना (machaanaa), the transitive causative counterpart ('to cause/create a commotion') -- शोर मचाना (shor machaanaa, 'to make noise') is what the noisy person does; शोर मचना (shor machnaa) is what happens as a result.
