How do Americans manage to pronounce the word "murderer

<<True, but I'd also add that in British dialects t's are rarely tapped. I've sometimes heard some t's tapped at the end of words, between a word and the following one, but never in the middle of a word (occasionally tapped in "might end" or "but in", but not in "matter" or "butter"). Am I right? >>

You'd find a tapped t in that position in Norther Ireland.

I wouldn't say rarely but just less frequently than in American dialects, and usually that's due to careful speech or the use of a glottal stop.

But logically, there isn't any difference when comparing the linking T of "but in" and "butter" in natural speech. A speaker might stress the first syllable in "butt in" and deliberately avoid a tap to distinguish it from "but in".

I think everyone should just stop using this word. It's a bad word. I hate it.

What about "rural"? I find it pretty difficult to say and I'm a native speaker.

I pronounce "woowol".
