Merriam-Webster, move over! Until now, no English dictionary ever found the fun or the fascination in revealing the meanings of letters. One-Letter Words, a Dictionary illuminates the more than 1,000 surprising definitions associated with each letter in the English alphabet. For instance, Conley uncovers seventy-six distinct uses of the letter X, the most versatile, most printed letter in the English language. Using facts, figures, quotations, and etymologies, the author provides a complete and enjoyable understanding of the one-letter word. Conley teaches us that each letter's many different meanings span multiple subjects, including science -- B denotes a blood type and also is a symbol for boron on the periodic table of elements -- and history -- in the Middle Ages, B was branded on a blasphemer's forehead. With the letter A, he reminds us that A is not only a bra size, but also a musical note.
