An extreme or irrational fear of demons or demonic things.
From demon + -phobia (from Greek phobos meaning 'fear'). This clinical-sounding term combines the standard phobia construction used for specific fears with demons as the object.
Demonophobia was probably super common in medieval times—people genuinely believed demons were everywhere—yet we don't really use the word now because we don't fear demons the same way, showing how words can become historically extinct even when you can perfectly understand their meaning.
