And nobody says "tsk"

I can be a bit slow on the uptake. Here’s a thing that finally occurred to me. When an British writer has somebody say “er,” they mean “uh” in American. When they write “fellers” they mean “fellas.” See, most British accents are non-rhotic, and “er” and “uh” are pronounced the same. Unless you’re the actor Robert Newton. He was from Shaftesbury in England’s West Country and exaggerated his native accent when he played Long John Silver in the movies, which is why we say “arrr” when we talk like pirates. This does not explain why some people pronounce “banana” “bahnahner.”
