Innit
What it really means
Short for "isn't it". Young people often add it to the end of any sentence to mean "right?" or to show agreement: "Cold today, innit." Very informal — avoid in essays or with tutors.
Context, tips & common mistakes
"Innit" started as London slang, strongly associated with Multicultural London English, and has spread among young people across urban Britain. Grammatically it has broken free of "isn't it": young speakers use it as an all-purpose tag after any sentence — "He works nights, innit" — where standard English would need "doesn't he". Two warnings for learners. First, it is very age- and register-marked: from a student in casual chat it sounds natural, but in an essay, an email or a conversation with staff it will jar badly. Second, non-native speakers who sprinkle "innit" deliberately often sound like they are performing Britishness rather than speaking it — locals notice. The safest approach is to understand it (you will hear it constantly) but use it rarely, and only once you are comfortable with the friends you are copying it from. Older Britons largely do not use it, and some actively dislike it.
