Common Abbreviations But We Don’t Know The Meaning

common abbreviations

We use common 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.

Familiar acronyms and abbreviations

Some forms use capital letters, but we pronounce them as words.

A good example is the North Atlantic Treaty Organisation, which forms the word NATO.

Other examples include NASA and POTUS. Radar is also an acronym derived from radio detection and ranging, but it doesn’t use all capitals.

However, for many, we pronounce them letter by letter.

We call The United States of America the US or the USA, the United Kingdom the UK, and the United Nations the UN.

Another type of abbreviation is one that comes from a foreign language. Very often, these are of Latin origin.

The most common are, e.g., exempli gratia, meaning for example or for instance, and, i.e., id est, meaning that or in other words.

We use abbreviations and acronyms all the time.

But we don’t always know where they came from, how they derived, or what they mean.

Here are examples of some very common acronyms and abbreviations we use but may not fully understand.

 

1. What does RSVP mean?

If you receive a wedding invitation, it often includes the term RSVP.

It asks you to use a response card and to please respond and advise us of your acceptance or inability to attend by a certain date.

A new form is RSVP, regrets only. Sometimes, this form only uses Regrets only.

The expression means you only need to advise if you cannot attend.

RSVP invitations are less common nowadays.

Surprisingly, although the term is an acronym of the French phrase, répondez s’il vous plaît, which means, please respond, the phrase is now a rarity in French.

More common in French today is the expression, Réponse attendue avant le.

It means responding by a certain date.

 

2. What does PS mean?

ps i love you

P.S. is one of the most common abbreviations we use for the Latin term post scriptum.

It means after what has been written.

We use it at the end of letters, in particular, to indicate an afterthought after writing the letter.

In modern communication, such as email and electronic documents, the use of P.S. serves little purpose any longer.

 

3. What does sic mean?

The most common form of the word sic is as an adverb to indicate an error in quoted material.

When quoting a person who makes a grammatical or pronunciation error, the person writing the quote inserts sic in square brackets.

It indicates that the quoted text includes errors made in the original quote.

Sic is a Latin word that derives from the expression sic erat scriptum.

It means, thus, it was written, or intentionally so written, and indicates that the mistake was in the original document and that it is not a misquote.

It is important to note that you should never write sic when referring to grammatical or spelling variations between British and American English.

While a word might be spelt or spelled incorrectly in US English, it is correct in British English.

The car’s front tyre was flat, so he got the spare from the boot. It would be inappropriate to include brackets or sic here to indicate misspelled words or incorrect use.

Nor would it be right to rewrite the quote and change it to the car’s front tire was flat, so he got the spare from the trunk.

Another more archaic use is, sic transit gloria mundi, which is an old Latin phrase that means, thus passes the glory of the world.

Sic is also a verb that means to encourage an attack, particularly by a dog. “Leave me alone, or I’ll sic my dog on you!”

 

4. What does et al mean?

We use Et al. for three Latin abbreviations.

They are, et alii meaning and others, in particular co-workers, et alia to indicate other things and et alibi for other places.

It is easy to confuse it with etc. et caetera, which also means and the others, other things, or and the rest. But we never use it to indicate other people.

 

5. What does SOS mean?

SOS

Although S.O.S. is a Latin abbreviation for si opus sit, meaning if there is a need, if the occasion requires, or if necessary, it is not the common use.

The SOS radio distress signal is the most common use of this abbreviation.

It is not unusual to think that SOS stands for save our souls or save our ship.

The SOS signal for a ship in distress was devised and based on International Morse Code and wireless telegraph.

The distress signal is three dots for the letter S, and three dashes for the letter O. This combination of dots and dashes was chosen because it was quick and simple for a telegraph operator to send.

This distress signal was first adopted by German government radio regulations in 1905 and became the international standard in 1908.

The steamer SS Arapahoe sent the first SOS distress signal on 11 August 1909.

The signal of the Arapahoe was received by the United Wireless Telegraph Company station at Hatteras, North Carolina, and forwarded to the steamer company’s offices.

At the time, there was another distress signal, CQD. Marconi International Marine Communication Company used it, and it became effective on 1 February 1904.

When the Titanic hit an iceberg, the telegraph operator aboard the ship at first sent CQD distress signals.

On April 15, 1912, RMS Titanic radio operator Jack Phillips initially sent “CQD,” which was still commonly used by British ships.

Harold Bride, the junior radio operator, suggested using “SOS,” saying half-jokingly that it might be his last chance to use the new code.

Phillips thereafter began to alternate between the two. Though Bride survived the sinking, Phillips did not. Source, Wikipedia.

During World War II, suffix codes were added to SOS. SSS indicated an attack by a submarine, RRR for a surface raider, AAA for air attack, and QQQ for an unknown attacker.

Between the two wars, the development of audio radio transmitters meant a spoken distress phrase was needed.

The word “Mayday” was the choice. It came from the French word m’aidez, which means help me. In 1927, the International Radio Convention adopted it as the equivalent of SOS.

 

6. What does Scuba mean?

Scuba diver

Scuba diving is well-known as a profession or a recreational activity.

How many people do you know who boasted about going scuba diving while on holiday?

But what does the word mean?

It’s an acronym that comes from the name and use of the equipment needed to breathe underwater.

Self-contained underwater breathing apparatus.

 

7. What does QED mean?

You can write Q.E.D. or QED and even use italics.

It is from the first letters of the Latin phrase, quod erat demonstrandum. Literally, it means what was to be shown, or therefore or thus it has been demonstrated.

You see it when placed at the end of a mathematical formula or statement to indicate that the proof is full and complete.

Douglas Adams used Q.E.D. in this quote from The Hitchhiker’s Guide to the Galaxy.

“‘I refuse to prove I exist,’ says God, ‘for proof denies faith, and without faith I am nothing.’ ‘But,’ says Man, ‘The babel fish is a dead giveaway, isn’t it?

It could not have evolved by chance. It proves you exist, and so, therefore, by your own arguments, you don’t. QED.’ ‘Oh dear,’ says God, ‘I hadn’t thought of that,’ and promptly vanishes in a puff of logic.”

 

Brief wrap-up on an Abbrev.

We use a lot of abbreviations, contractions, and acronyms without thinking about what they denote.

A handful of examples are:

N.B. nota bene, meaning, please note well.

A.M. ante meridiem for before midday, and P.M. post meridiem for after midday.

AD anno Domini, meaning in the year of the Lord.

However, BC is not Latin. It stands for before Christ.

It is worth noting that BC comes after the year number while AD is before the year—for example, AD 1976, but 250 BC. Also, unusually, neither uses periods (full stops).

  1. I knew most of these, but not sic.
    On US and UK English. I am from the UK and use UK English because I don’t know all idioms and spellings in the US, so don’t even attempt it. A mixture would be wrong. Fortunately, I’ve not written any novels set in the USA.

  2. Useful and interesting. I did not know the original Latin source of SOS.

    I tend to disagree on the correction of UK or US English as applicable. As an editor, I make sure books are in one or the other. I have had some authors who have written two or more narratives in one novel, set on either side of the Atlantic, and I have ensured that they have stuck to the spelling and idiom appropriate to each.
