A verbivore, according to the Grandiloquent Dictionary (http://www.islandnet.com/~egbird/dict/dict.htm) is a person who devours words. I'd say that is a good description of me, as well as many of my acquaintances who love to write. Few things give me more pleasure than finding just the right word for a situation.
I chose this word because, to be perfectly honest, I couldn't come up with a unique topic for the letter V. Since I love words so much, I decided to fall back on my old habit of just looking through lists of words to find the one I wanted, and found verbivore.
