We have talked a whole lot about silent letters in English here on the Ginseng English blog.
But, as a recent article in Reader's Digest points out, nearly every letter in the English language is silent sometimes. There is only one letter in the language that is never silent. Can you guess what it is?
The letter is V! There are various very valuable v-words, and that V is never silent!
If you're thinking, "Wait, but what about A!? What about X!?" you can check out Wikipedia's list of silent letters from A to Z. (You might notice that they do have something listed under V, but it's the name of a town in Scotland, which isn't exactly an English word in the way we generally think of things.)
