Richard Lederer's Verbivore
"The web site woven for wordaholics, logolepts, and verbivores. Carnivores eat meat; herbivores eat plants and vegetables; verbivores devour words. If you are heels over head (as well as head over heels) in love with words, tarry here awhile to graze or, perhaps, feast on the English language. Ours is the only language in which you drive in a parkway and park in a driveway and night falls but never breaks and day breaks but never falls."
Word Detective
