A: How do I improve my Cockney accent?


Q: If cockneys drop the "h" and don't pronounce it, do they still use "a" instead of "an" in words like: a hat, a house. Because it would sound like: a at, a ouse. Thanks.
A: Na they keep it the same, so it'd be like: an ouse (house), an at (hat), an ose (hose pipe).

They also pronounce the F word (I won't say it just in case) differently. They swap the U for an A.

In addition, you also have rhyming cockney slang, like "Apples and pears" (stairs), brown bread (dead), half inch something (to pinch/steal something) - pronounced "alf" rather than half. Can't remember any others.

They also use the word "ain't" a lot. So "I'm not doing that" could be "I ain't doing that".

Good luck, British and Irish slang is awesome

Q: would you recommend to learn the cockney accent ?? I mean is it used these days? which accent will make me sound native Londoner?
A: I do not recommend you learn the cockney accent. Most Londoners do not speak with a cockney accent. Also I personally think you can only sound like a native after living in a place for a significant amount of time. Keep your accent! Like Georgieboi said as long as you can be understood that's all that matters. :)
