Hippopotomonstrosesquippedaliophobia

Hippopotomontrosesquipedaliophobia (or sesquipedalophobia) is one of the most ironic and unusual fears of them all. It is the fear of long words. Anyone with this fear may become very stressed when they try to say a long word, and it may be hard to explain to a doctor or therapist about this fear, as they are to stressed to even say it.
