n. A person who uses long words, or a long word, itself.
A pseudointellectual often tries to be sesquipedalian, but is not sufficiently pedantic to know how the words should actually be used. (As with the famous Damon Wayans sketch, at right)
Roman poet Horace coined the term while mocking words “a foot and a half long”; sesqui – “half again”, pedi – “foot”. The full phrase was actually sesquipedalia verba.
