Etymology

Origin of acrophobia

First recorded in 1890–95; acro-, -phobia

Explanation

Want to go to the top of the Empire State Building? You must not have acrophobia. Someone who is terrified of heights will just wait for you in the gift shop — which is on the ground floor. You can see the word phobia, or extreme fear, in acrophobia. Acro comes from the Greek word akron, which means "summit" or "high point." When you put it all together, you have a word that means "fear of heights." Whoever named Akron, Ohio, must have studied Greek; it is located on a plateau in Summit County.
