झूठ (jhooth)

noun/adjective Primarily a noun meaning 'a lie/falsehood,' with a very common adjectival/adverbial use meaning 'false, untrue' -- as in बोलना (jhuuth bolnaa, 'to tell a lie'). Both senses share the same root idea, just different grammatical jobs.
Sense 1 : a lie, falsehood
noun, masculine
Synonyms: मिथ्या (mithyaa, literary), असत्य (asaty, formal)
Frequency: high
Cultural Note: Every Hindi-speaking kid has heard झूठ मत बोलो (jhooth mat bolo, 'don't lie') from a parent or teacher at some point -- it is one of the first moral instructions given to children. The classic idiom सफेद झूठ (saphed jhooth, 'a white lie,' literally 'a white/blatant lie') is used ironically in Hindi to mean a bald-faced, shameless lie -- the opposite of the English 'white lie' as something harmless.
Common Mistakes: 1) Learners often say कहना (kahnaa) for 'to tell a lie' by direct translation from English, but the native collocation is झूठ बोलना (jhooth bolnaa, 'to speak a lie') -- बोलना (bolnaa), not कहना (kahnaa), is the verb that pairs with झूठ (jhooth). 2) झूठ (jhooth) itself is often used without an article, more like a mass noun ('falsehood') than 'a lie' -- so झूठ मत बोलो (jhooth mat bolo, 'don't lie') is far more natural than trying to say 'a lie' with a number word.

Sense 2 : false, untrue
adjective In this sense झूठ (jhooth) functions as an invariant qualifier, often right before a noun or verb, distinct from its inflecting cousin झूठा (jhoothaa) which is the more standard attributive adjective form.
Synonyms: झूठा (jhoothaa, more common as attributive adjective), गलत (galat, meaning scope: 'wrong/incorrect' rather than 'false')
Frequency: medium
Cultural Note: You will often hear झूठ (jhooth) used almost adverbially in casual speech, as in झूठ ही बोल रहा है (jhooth hii bol rahaa hai, 'he's just lying/talking nonsense') -- a slightly dismissive, everyday way to call out something as untrue.
Common Mistakes: 1) Learners sometimes confuse this bare झूठ (jhooth) with झूठा (jhoothaa) -- both can mean 'false,' but झूठा (jhoothaa) inflects for gender/number when modifying a noun (झूठी कहानी jhoothii kahaanii, 'false story'), while झूठ (jhooth) itself does not change form.
