What's up?
One of the surprisingly large number of two-letter words in the english language. Not one of the even more surprising subset of those that do not contain a vowel, or even a "y". For example "sh" is a word. Offhand, I can't recall how many such I found in Chambers, but somewhere around here I have the 26x26 grid on which I marked them all. Shall I go look for it? I'll happily draw it up again if you wish. I doesn't take long.
