Definition & Meaning of "Innit?"in English

What does "innit?" mean in British slang?

The structure is a contracted, informal reduction of "isn't it," often used as a fixed tag question. It is used for emphasis or to seek agreement, typically at the end of a statement, functioning similarly to "right?" or "you know?" in other dialects. People typically say "It's cold today, innit?" or "That film was good, innit?" The term originated in working class British English, particularly in London and Multicultural London English (MLE), during the late 20th century, and has since spread across the UK as a versatile, almost meaningless tag for affirmation or confirmation.
