ABECEDARIAN: An abecedarian is a beginner, like someone who is just learning the A-B-C's of the alphabet. SESQUIPEDALIAN: A sesquipedalian is someone who uses big words. The Roman poet Horace used this long word to warn other poets against using foot-and-a-half long words. In Latin, sesqui- means “one and a half” and pedal-ian means “relating to the foot” (think pedal on a bicycle). HONORIFICABILITUDINITATIBUS: For over a thousand years, this Latinesque word has been used as an example of a humorously long word. It is semi-nonsensical, but more or less means "being in the state of being able to be honored", or honorable. William Shakespeare famously used the word in his play, Love's Labour's Lost.
