Where do people speak cockney?

Cockney is a dialect of English traditionally spoken in the East End of London, England. While it's not as prevalent today as it once was, it's still spoken by some people in the area.

It's important to note that:

* Cockney is not a separate language. It's a dialect of English, meaning it has its own vocabulary, pronunciation, and grammar rules.

* Cockney is not just about rhyming slang. While rhyming slang is a famous aspect of Cockney, it's not the only feature.

* Cockney is evolving. The dialect is constantly changing, and its use has declined over time.

While you might hear some remnants of Cockney in the East End, it's not as common as it used to be. Modern media often portrays Cockney in a caricatured way, which doesn't necessarily reflect the reality of the dialect.
