Sesquipedalian

I came across this word the other day--sesquipedalian.  Click link to learn the pronunciation .  This adjective means given to using long words.

When looking this up, I found the following site about long words:  Long Word Flashcards .  I wonder if I would ever use any of the seven words posted with the exception, of course, of singing **Supercalifragilisticexpialidocious.**
