अवैध (avaidh)

adjective A formal adjective meaning 'illegal, unlawful' -- the negative prefix अ- (a) attached to वैध (vaidh, 'legal/valid'). One sense only, but common in news and official contexts.
Sense 1 : illegal, unlawful
adjective
Synonyms: गैरकानूनी (gairkaanoonii), गैरक़ानूनी (gairqaanoonii, variant form), नाजायज़ (naajaayaz, colloquial)
Frequency: medium
Cultural Note: You will meet this word constantly in newspaper headlines and TV news tickers -- अवैध (avaidh) कब्ज़ा (kabzaa, 'illegal occupation/encroachment') and अवैध (avaidh) निर्माण (nirmaan, 'illegal construction') are staple phrases in Delhi-NCR coverage of land and building disputes, given how often such stories make the local news here. In everyday speech people often reach for the more casual गैरकानूनी (gairkaanoonii) or नाजायज़ (naajaayaz) instead, keeping अवैध (avaidh) for a slightly more official or written register.
Common Mistakes: 1) Learners sometimes reach for गलत (galat, 'wrong') to mean 'illegal', but गलत (galat) covers mistakes and errors generally, while अवैध (avaidh) is specifically about breaking law or rule -- an अवैध (avaidh) निर्माण (nirmaan, 'construction') is one built without legal permission, not a badly built one. 2) In casual speech, नाजायज़ (naajaayaz) is often heard instead of अवैध (avaidh) for the same idea; अवैध (avaidh) itself stays on the more formal, written/news side.
