Innit, though
Interesting post today on the British Library’s Sound Recordings Blog, which explores the term ‘innit’. Obviously this word is one I have looked into a great deal, mostly during the writing of We’re British, Innit. I first came across it being used by members of the Greek community (immigrants and second generation) in Thanet, where I grew up. Though I do have some memory of it being in use in Cockney and London/Kent English before that, especially as depicted in uses of slang in popular culture.
You can hear it being used by, I think, Keith Moon, in this very odd 1966 Who track. Though there are examples in film going back to the 1950s at least.
