The Online Etymology Dictionary is lovely, very nicely designed visually and structurally, and vast in content.
The Online Etymology Dictionary is the work of one person, a newspaper copy desk editor, who wishes to remain nameless—or at least hard to identify. The long "who did this" page gives many biographical details, just not the ones you would expect. The dictionary is lovely, very nicely designed visually and structurally, and vast in content. If you are interested in the history of words, you won't be disappointed.
A quote from the author: "Etymonline is a can-opener, an imaginary labyrinth with real minotaurs in it, my never-written novel shattered into words and arranged in alphabetical order."
