Definition & Meaning of "abbreviation"in English

What is an "abbreviation"?

An abbreviation is a shortened form of a word or phrase, created by using only a few of its letters or syllables to make it quicker to write or say. Common examples include "Dr." for "Doctor" or "etc." for "et cetera". Some abbreviations are formed by taking the initial letters of a series of words, such as "NASA" for "National Aeronautics and Space Administration". Abbreviations are widely used in everyday language, writing, and specialized fields to save time or space while still conveying the full meaning of the original term.
