Radar, laser, scuba. Did you know that these words are acronyms? What is an acronym?
Acronyms are words that are formed by the first letters of each word in a phrase. Strictly speaking, acronyms are pronounced as one whole word.
You’ve probably read LOL in text or chat messages. It’s an acronym for “laughing out loud” or “lots of laugh.” It’s now pronounced as “lawl.”
Many English words are actually acronyms. Here are some examples:
1. radar – This is the word for the device that sends out radio waves so you can find out the position and speed of a moving object, like an airplane. Radar stands for “radio detection and ranging.” This word was invented in the 1940s.
2. laser – This is the word for the device that makes powerful beams of light. It is an acronym for “light amplification by stimulated emission of radiation.” It was created in the 1960s.
