Acronym

nounPronunciation: /ˈæk.rə.nɪm/

In Portuguese: Sigla

What does “Acronym” mean?

A word formed from the initial components of a longer name or phrase. It simplifies complex institutional designations into recognizable units.

Etymology

A 20th-century formation from Greek akron ("tip, end") and onyma, a dialect form of onoma ("name"), on the model of words such as synonym and homonym. German has the parallel Akronym. The word spread in English around the middle of the century, when names built from initials multiplied in government, the military and industry.

Usage note

In strict use an acronym is pronounced as a word (NASA, radar); in everyday use the term covers any abbreviation made of initials.

Synonyms

  • initialism
  • abbreviation

Often confused with

initialism
An initialism is read letter by letter (ESG, FBI); an acronym, in the strict sense, is read as a word (NATO, laser).

Word family

  • acronymic

Usage examples

  • ESG is an acronym as much as I just turned it into a verb.
