Acronyms - What They Are and How to Use Them
An acronym is a way of abbreviating a series of words by using the capital letters from each individual word. So, for example, the phrase ‘Chief Executive Officer’ may be abbreviated (and often is) to ‘CEO.’ Some words in common usage such as ‘AIDS’ are acronyms. The word ‘AIDS’ is therefore an abbreviation of the term ‘Acquired Immune Deficiency Syndrome.’ This is then abbreviated to ‘AIDS’. The acronym is denoted by the use of the capital letters.
However, not all acronyms have capitalisation. Some words are now in such common usage that they are now always written in lower case. For example, ‘laser’ is an acronym and it stands for ‘light amplification (via) a source of emitted radiation.’ The word started off being expressed as an acronym and was then simply transferred into everyday usage. There are quite a few acronyms that have entered the language in this way, but are now regarded as normal words, as opposed to acronyms.
The internet and computer technology have resulted in many new acronyms being introduced into the language and these may not be understood by offline punctuation checkers, but will be identifiable to most online grammar programs and punctuation applications.
Generally when using acronyms caution must be exercised, since the acronym may not be readily understood by everyone, particularly in written English. So, if you do want to use one, then use an online punctuation or grammar checker, just to ascertain if it is actually a known acronym that everyone will be able to understand. Otherwise, their use should generally be avoided.
