बेवफ़ाई (bevfaaii)

noun A single-sense noun meaning 'unfaithfulness, disloyalty, betrayal' -- especially in love or friendship. Built from बे- (be-, 'without') plus वफ़ा (vafaa, 'faithfulness') plus the abstract-noun suffix -ई (-ii).
Sense 1 : unfaithfulness, betrayal (especially romantic)
noun, feminine
Synonyms: धोखा (dhokhaa, everyday word for betrayal/cheating), दगा (dagaa, somewhat literary), विश्वासघात (vishvaasghaat, formal)
Frequency: high
Cultural Note: This word lives most vividly in Bollywood songs and shayari (shaayrii) about broken hearts -- it is the standard word a jilted lover uses, carrying more emotional weight than a plain 'cheating' would in English. Its opposite, वफ़ा (vafaa) or वफ़ादारी (vafaadaarii), 'loyalty/faithfulness,' is worth learning alongside it since the two are constantly paired in song lyrics and conversation.
Common Mistakes: 1) Learners often reach for धोखा (dhokhaa) as a catch-all for 'betrayal,' but बेवफ़ाई (bevfaaii) is specifically the *quality or state* of being unfaithful (often in love), not a single act of deception -- so it pairs naturally with करना (karnaa) as 'to be unfaithful/commit betrayal,' whereas धोखा (dhokhaa) more often describes one concrete deceptive act. 2) The person being betrayed is usually marked with से (se), as in किसी से बेवफ़ाई करना (kisii se bevfaaii karnaa, 'to be unfaithful to someone') -- learners sometimes reach for को (ko) instead.
