Thanks to Tom Sarbeck for saying this of our hard-to-find dictionary of one-letter words:

Compiler Craig Conley says, "In Shakespeare's time, R was called littera canina, 'the dog's letter,' because it sounded like a dog's growl."

There may be word lovers who won't read stuff like that; I'm not one of them.

Conley provided me with more motivation to buy his dictionary's Kindle edition; he said that since he wrote its first edition he hasn't had to buy a single drink.
