We use abbreviations and acronyms all the time, but what do they mean?
The English language uses many forms of word abbreviation.
We use shortened forms increasingly for text messaging to reduce a word or phrase.
Very often these are acronyms using initial letters such as LOL, ROTFL and BRB.
Other forms also use a capital letter from the start of each word but are pronounced as words. A good example is the North Atlantic Treaty Organisation, which forms the word, NATO.
Other examples are NASA, POTUS and SCUBA. If you didn’t know, SCUBA means self-contained underwater breathing apparatus. Radar is also an acronym, derived from radio detection and ranging.
Many common abbreviations, however, are pronounced letter by letter. The United States of America is most commonly referred to as the US or the USA, the United Kingdom as the UK and the United Nations as the UN.
