Abbreviations and acronyms are a short way to represent a word or a phrase.


An abbreviation is a shortened form of a word or phrase: to form it, we take some letters from the word or phrase.

Acronyms are words created with the initial letters of multiple words that denote a single thing.


  1. Abbreviations:
    • dr = doctor;
    • km = kilometre;
    • 10 am = ante meridiem (latin) – before midday.
  2. Acronyms:
    • EU = European Union;
    • USA = United States of America;
    • UK = United Kingdom.


We use abbreviations and acronyms to save time and space when writing and some standard ones when speaking (am, PhD etc.).

Avoid using abbreviations in formal writing. Also avoid using too many abbreviations in one text because it makes it difficult for the reader to follow.

When you want to form the plural version of an abbreviation, just add an s at the end.
