Abbreviations are shortened versions of words or phrases. There are many abbreviations which are used frequently in English, most of which are derived from Latin. Infact, the word ‘abbreviation‘ is derived from the Latin word brevis, which means short.
You may be aware of many of the most common abbreviations used but I am sure you will find this list useful nevertheless ![]()
Please note, in the past all abbreviations had a full stop (period) at the end of it but this isn’t always the case now and sometimes the full stop is dropped. Also, many people recommend adding a comma after an abbreviation.
- etc – Short for ‘et cetera‘, which is the Latin phrase for ‘and other things‘ or ‘and so forth‘. Example : 4, 5, 6 etc.
- i.e. – Short for ‘id est‘, which is the Latin term for ‘that is‘ or ‘in other words‘. Example : I went back to writing on my usual blogging device i.e. my laptop. This abbreviation is commonly confused with e.g. (and vice-versa).
- e.g. – Short for ‘exempli gratia‘, which is the Latin phrase for ‘for example‘. Example : The man was rich enough to buy his own basketball team e.g. the New York Knicks.
- p.s. – Short for ‘post scriptum‘, which is the Latin phrase for ‘after writing‘. It is an afterword which is added at the end of a text. Example : p.s. I wrote this article with my left hand. Additional afterwords add an extra P ie. p.s., p.p.s.,p.p.p.s. etc.
- N.B. – Short for ‘Nota bene‘, which is the Latin phrase for ‘note well‘. It’s used to remind the reader not to forget something important. Example : N.B. Always make sure you wash your hands before you leave the bathroom!
- cf. – Short for ‘confer‘, which is the Latin phrase for ‘compare‘ or ‘consult‘. It is very common in academic papers, journals and other types of reference publications e.g. dictionaries. It is used to draw the readers attention to additional information. Example : cf. page 405.
- p.p. – Short for ‘per procurationem‘ (‘per pro‘), which is the Latin for ‘to behalf of‘. It is used frequently in business letters. For example, a secretary sending out a letter on behalf of the company CEO would p.p. her name to the bottom of it to show that they have written the letter on behalf of the CEO.
- viz. – Short for ‘videlicit‘, which is the Latin phrase for ‘it is permitted to see‘, ‘as befitting‘ or ‘as is pleasing to‘. In English it is usually read as ‘namely‘ and is mostly used in the same way as i.e., Example : He was sent to the principles office viz. Mr Jones.
- et al. – Short for ‘et alii‘ which is the Latin phrase for ‘and others‘. ‘Alii‘ is the masculine form so when referring to a female you should use ‘et aliae‘. The neutral form ‘et alia‘ can be used when referring to a lot of people. Example : The song proved to be popular with football fans et al.

Great list Kevin … I can see that I use the i.e. and e.g. incorrectly some times … so I'll need to bookmark this list and get those memorized. The others I don't use as much or I guess when I do I use them correctly … but it is a great list and facinating to see the "real" meaning and where they were derived. Thanks. *SmiLes* Suzanne
