List of Commonly Used Abbreviations

Abbreviations are shortened forms of words or lengthy phrases. You'll find them in almost every discipline and area of life, from commonly used abbreviations in names or titles, such as Mr. for Mister or Sgt. for Sergeant, to less commonly used abbreviations, such as the shortened version of the word abbreviation itself, which is abbr.

There is more than one type of abbreviation. An acronym is a new word created from the initial letters of a long name or phrase, for example, NATO (North Atlantic Treaty Organization). An initialism is where a long phrase is abbreviated to its initial letters but the letters are pronounced individually, not spoken as a word, for example, FBI (Federal Bureau of Investigation). An initialism can be considered a type of acronym.

The U.S. is itself a well-established abbreviation. As you will see in the following list of commonly used abbreviations they exist in all areas of life from medicine to military and geography to baking.

Alphabet Agencies

During the Great Depression, President Franklin Delano Roosevelt created a number of agencies to stimulate job growth in the United States. Known as "alphabet agencies," these are some of the most famous abbreviations today.

  • AAA - The Agricultural Adjustment Act. This act was created in 1933 to compensate farmers for not planting crops as a way to increase the demand for certain agricultural products and raise prices. By 1936, the Supreme Court ruled that the act was to be voided.

  • CCC - The Civilian Conservation Corps. Single men between 18-25 were selected to form this corps, which would work on conserving wildlife and national preservation areas, in addition to planting trees and fighting erosion.
  • CWA - The Civil Works Administration. Four million people were employed by the CWA to work in renovation and construction jobs such as building repair, road building, and other infrastructural work.
  • FDIC - The Federal Deposit Insurance Corp. Since banks were widely distrusted after the many bank failures during the depression, this alphabet agency was created to encourage public confidence in banks again by insuring customers against losses of up to $5,000 if the bank happened to fail.
  • FHA - The Federal Housing Administration. This organization was created to help people secure loans to buy houses.
  • NRA - The National Recovery Administration. In 1933, the NRA was created to attempt to aid deflation and encourage market competition, in order to restore the economy. Unfortunately, the administration did not stimulate industrial production, although investor and consumer confidence were restored.
  • SSA - The Social Security Administration. The Social Security Act, administered by the Social Security Administration, created a national pension for retired people as well as unemployment insurance and government aid for single mothers, children, and handicapped persons.

Understanding Latin-based Abbreviations

Looking at Latin, the root of much of the English language, is a good way to decipher abbreviations. The most common abbreviations that we use in day-to-day life are derived from this ancient language. For example:

  • AM/PM - AM, which we use to denote morning, is an abbreviation for ante meridiem (before noon), and PM stands for post meridiem (after noon).
  • AD - 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 we use so frequently that, at times, we forget what they stand for. For instance:

  • e.g. - You will often see the abbreviation e.g. before someone gives an example. It stands for exampli gratia, which means, "example given."
  • etc - "Etc", often seen at the end of long lists, is short for etcetera, which means "and other things."
  • i.e. - Another popular abbreviation we use in daily life, i.e. stands for id est, meaning, "that is."
  • n.b. - This is sometimes written at the end of a communication that needs special attention. It stands for nota bene, which means "take notice," or "note well."
  • P.S. - At the end of a letter or email, people will often add a P.S. to include an additional comment or thought. It is short for post script, which means "written after."
  • Viz - Another Latin abbreviation you may see is "viz", which is short for videlicet, meaning "namely."

Abbreviations have become an inalienable part of our lives, they save us time and space in our written communication. In other words, almost anything you want to do will require you to know an abbreviation or two.
