There are a lot of unsual phobias out there.
Didaskaleinophobia is for instance the school phobia, that’s to say the fear of going to school.
Neophobia is the fear of anything new. Endrophobia is the fear of trees.
Hippopotomonstrosesquipedaliophobia is a kind of phobia !
But The length of the word can make a healthy humane fall in the phobia ! that’s pretty ironic.
