When we think of names, we often refer to just first names, middle names, or last names. But there’s a much wider world of naming terminology! From acronyms that shorten phrases into memorable identifiers, to zoonyms that describe animals by name, linguists and writers use dozens of specialized terms to categorize the types of names we encounter on a daily basis. This glossary explores the many categories of names, giving you a clear guide from A to Z through the fascinating study of onomastics.
Acronym – A word formed by the first letters of a group of words, name or phrase. Examples: NASA (National Aeronautics and Space Administration) or SCUBA (Self Contained Underwater Breathing Apparatus). Make sure your baby’s initials don’t spell out an embarrassing acronym! (Also see Backronym)
Alliterative Name – Two names starting with the same letter. Example: Marilyn Monroe, Joe Jonas, Pepper Potts. Alliterative names tend to be more memorable, for both humans and fictional characters.
Anonym – Without a name. The word “anonymous” is used in place of a name in a published work or quote with no known author, or for an author who prefers not to be named.
Appellation – A name or a title given to a person OR a thing. So an appellation could be “The Sound of Music”, “The Windy City” or “Miss America.”
