[ Date: 1800-1900 ; Origin: isn't it ]
1 . used as a way of saying 'isn't it':
It's cold, innit?
2 . used after a statement for emphasis, instead of any ↑ question tag . This use is very non-standard and is grammatically incorrect, but has become common in spoken English among some young people:
He's a bad man, innit (=used instead of 'isn't he'.)
