List of Commonly Used Abbreviations

Written and verbal communication often includes these abbreviations:

R.S.V.P. – This acronym means "Répondez s'il vous plait," French for "respond, if you please." It is often used on invitations to parties and special events, and is intended (as it says) to be responded to with a "yes, we will attend," or "no, we will not."
P.S. – Means "post script." At the end of a letter, people will often include a P.S. to include an extra thought that was intended to be included in the letter, but forgotten. Using a P.S. was more common in typewritten letters, when you couldn’t go back and add a sentence in the body of a letter.
A.S.A.P. – "As soon as possible," used when encouraging someone to respond to a request without delay.
E.T.A. – This acronym means "estimated time of arrival," and is used as a guess for when one expects to arrive while traveling.
B.Y.O.B. – "Bring your own bottle" is used for parties where guests are expected to bring their own beverages.
D.I.Y. – This acronym stands for "do it yourself," which means creating something on your own. It is often used for crafts and home repairs.
AM, which we use to denote morning, is an abbreviation for ante meridian, and PM stands for post meridian.
The era in which we live, AD, is actually an abbreviation for Anno Domini, or “The Year of Our Lord.”

Latin has also gifted us with other abbreviations that we use so frequently that at times, we seem to forget what they stand for such as:

When someone quotes an example and uses the abbreviation e.g. to express it, it stands for exampli gratia, which means, "example given."
Also, i.e., another equally popular abbreviation we use in daily life, stands for id est, meaning, "that is."
"Etc", which is used also used often, is short for etcetera, which means "and other things."
Another popular Latin abbreviation we use in our daily life is "viz", which stands for videlicet, meaning "namely."
Other popular Latin abbreviations include n.b which is written at the end of a communication. It stands for nota bene, which means "take notice," or "note well."
