Hippopotomonstrosesquippedaliophobia: The Ironic Fear of Long Words

Hippopotomonstrosesquippedaliophobia is a constructed term (not in DSM-5 or ICD-11) meaning "fear of long words" — ironically, it is one of the longest words in English. The recognized clinical term is sesquipedalophobia.

Specific phobias require marked fear/anxiety about a specific object/situation, out of proportion, causing avoidance/distress. If long words truly trigger this, CBT/exposure therapy is effective. Mostly, it's a linguistic curiosity.
