Is "R" a Vowel?

You can often tell where someone is from by the way they pronounce the letter "r." Bostonians and the British don't pronounce it at all when it's in a word, but sometimes tack one on the end of a word when you least expect it. But some linguists say that under some circumstances, "r" can be a vowel. That theory won't change our spelling, and probably won't change any pronunciation. The series Storied from PBS explains the different ways different languages and cultures use "r" and how it could be considered a vowel, under the strange standards of linguistics.
