The Phobia List has hundreds (or thousands, I didn’t count them) of named phobias. If you are afraid of anything at all, it probably has a name here somewhere. Use the reverse list to find what you’re afraid of alphabetically, and it will tell you the name of your phobia. Buzzfeed illustrated some of the weirder ones.
The name for the fear of long words is just plain mean, don’t you think? And the fear of sitting down should have been named cat-here-o-phobia, or maybe spelled cat-hiss-o-phobia. See, the fear of sitting down can easily be initiated by the act of sitting on a cat.
