backronym

American  
[bak-ruh-nim] / ˈbæk rə nɪm /

  1. an existing word turned into an acronym by creating an apt phrase whose initial letters match the word, as to help remember it or offer a theory of its origin. For example, rap has been said to be a backronym of “rhythm and poetry.”

Usage

What does backronym mean? A backronym is an existing word that has been artificially made into an acronym, typically by matching each letter in it to a word to make a phrase that’s somehow related. An acronym is a word formed by abbreviating a phrase by combining certain letters of words in the phrase (often the first initial of each) into a single term. NASA is an acronym for National Aeronautics and Space Administration. To be clear, in backronyms, the letters don’t actually stand for the words they’re claimed or said to. Forming backronyms can be done for several reasons, such as to help remember how to spell the word, or, more frequently, to suggest a humorous or intentionally misleading explanation of its origin. A classic example of a misleading backronym involves the word posh, meaning “luxurious,” which is sometimes claimed to have come from an abbreviation of the phrase port out, starboard home. The story goes that the wealthiest passengers of ships would get to stay in cabins that faced this direction, and their tickets would be stamped with the letters POSH to indicate this—the supposed origin of the term posh. It’s possible that those letters have been stamped on a ticket, but there’s simply no evidence that this is where the word posh comes from. Less commonly, backronym is spelled bacronym. Example: I just saw a post claiming that the word car was originally an acronym for “catch a ride,” and I had to explain that it was a totally bogus backronym.

Etymology

Origin of backronym

First recorded in 1980–85; back 1 ( def. ) + (ac)ronym ( def. )

Explanation

A backronym is a phrase invented to explain what a word that looks like an abbreviation means. The Morse code signal "SOS" was created in 1905 as a distress call because it was easy to remember, but people later created the backronym "Save Our Ship" to explain its meaning. The word backronym is a portmanteau of back and acronym, which is a word created by taking the first letters of a phrase (e.g., NASA for National Aeronautics and Space Administration). A backronym goes in reverse: You invent a phrase that fits a term that looks like an acronym. Some backronyms are mistakes based on misunderstandings, such as thinking that "tip" stands for "to insure promptness." But some backronyms are intentional: The creators of the programming language known as BASIC named it that to indicate that it was simple enough for students to learn and use. They created the backronym Beginner's All-purpose Symbolic Instruction Code to fit the letters.
