Psychologists now tend simply to use the word phobia preceded by the name of whatever it is that a person has a phobia about. Since so few people now study Greek, there seems no particular merit in telling people with an irrational fear of cats that they have ailurophobia or those with a fear of riding in Vehicles that they have amaxophobia. There are some well-characterized phobias for which the technical name still has a specific usefulness such as claustrophobia and agoraphobia, but phobias are so varied that there is little point in inventing any more fancy polysyllables.
