Lincoln Punch“How do you pronounce those words in American English?”
There are basically six "R-colored vowels" in American English, represented by the sequence:
Sharp thorns tear poor deer's fur.
(tear in the sense of rip)
You can look up these six words and listen at www.m-w.com if you want to hear them.
(Use thorn, deer, not thorns, deer's, of course.)
You may want to memorize the sequence (or another of your own invention) as your personal reference and guide to those six sounds.
The sound in murder matches the one in fur.
The one in order matches the one in thorns.
The ones in regularly and particularly both match tear or fur, depending how fast you're talking.
