acronym
Definition - A word formed from the first letters of other words and pronounced as one word.
Note: This is in contrast to an initialism, which is a word also formed from the first letters of other words, but whose letters are pronounced separately, as in BBC (bee - bee - cee).

Example -

(1) NATO (North Atlantic Treaty Organization)
(2) LASER (light amplification by stimulated emission of radiation)

Etymology -

According to Fischer and Roswitha in Lexical change in present-day English (1998), the word was coined in 1943 by Bell Laboratories.
Ultimately, it derives from the Greek akros, tip or end + the English combining form onym, name.

Oxford English Dictionary -
Its first citation is from 1943:
"Words made up of the initial letters or syllables of other words … I have seen … called by the name acronym."

Note: Acronyms were initially called protograms, a term whose first OED citation is from 1924.

1. Two of my favorite acronyms are TLA (three letter acronym) and AFLA (another four letter acronym).

2. No, no, no, Norby Fleisig! TLA & AFLA are not acronyms. They are a different type of abbreviation: initialisms. Please re-read the definition & help stem the spread of this mis-use. Wikipedia says of "TLA": "Most three-letter abbreviations are initialisms: all the letters are pronounced as the names of letters, as in APA.... Very few fit the strict definition of acronym, which requires the abbreviation to be pronounced as a single word, as in DOS."
