acronyms is a distinctly twentieth- (and now twenty-first-) century phenomenon. There is only one
known pre-twentieth-century [English] word with an acronymic origin and it was in vogue for only a
short time in 1886. The word is colinderies or colinda, an acronym for the Colonial and Indian
Exposition held in London in that year."
The widespread, frequent use of acronyms and initialisms across the whole range of registers is a
relatively new linguistic phenomenon in most languages, becoming increasingly evident since the
mid-20th century. As literacy rates rose, and as advances in science and technology brought with
them a constant stream of new (and sometimes more complex) terms and concepts, the practice of
abbreviating terms became increasingly convenient. The Oxford English Dictionary (OED) records
the first printed use of the word initialism as occurring in 1899, but it did not come into general use
until 1965, well after acronym had become common. By 1943, the term acronym had been used in
English to recognize abbreviations (and contractions of phrases) that were pronounced as words. (It
was formed from the Greek words ἄκρος, akros, "topmost, extreme" and ὄνομα, onoma, "name.")
For example, the army offense of being absent without official leave was abbreviated to "A.W.O.L."
in reports, but when pronounced as a word ('awol'), it became an acronym. While initial letters are
commonly used to form an acronym, the original definition was a word made from the initial letters
or syllables of other words, for example UNIVAC from UNIVersal Automatic Computer.
Acronym is way to form word, it is similar to abbreviation, when each first letter of the source
word is taken and to form new acronym. In English we can find like NASA (national aeronotics and
space administration), VIP (very important person), NATO (north Atlantic treaty organization), etc.
Acronym is forming words from the initials of a group of words that designate one concept. Usually,
but not always, capitalized. An acronym is pronounced as a word if the consonants and vowels line
up in such a way as to make this possible, otherwise, it is pronounced as a string of letter names.
Acronyms and initialisms are abbreviations formed from the initial letter or letters of words, such as
NATO and HTML, and are pronounced in a way that is distinct from the full pronunciation of what
the letters stand for. Of the two words, acronym is the much more frequently used and known, and
many speakers and writers refer to all abbreviations formed from initial letters as acronyms.
However, many others differentiate between acronyms and initialisms. An acronym is a
pronounceable word formed from the initial letter or letters of the constituent words, such as NATO.
An initialism is an abbreviation pronounced as the names of the individual letters, and is formed only
from the initial letter of constituent words, such as TLA. This distinction is supported by many
dictionary definitions, but not by all.
Although the term acronym is widely used to describe any abbreviation formed from initial
letters, some dictionaries define acronym to mean "a word" in its original sense, while some others
include additional senses attributing to acronym the same meaning as that of initialism. The
distinction, when made, hinges on whether the abbreviation is pronounced as a word, or as a string of
letters. According to the first definition found in dictionaries, examples of acronyms are NATO
(/ˈneɪtoʊ/), scuba (/ˈskuːbə/), and radar (/ˈreɪdɑr/), while examples of initialisms are FBI (/ˌɛfˌbiːˈaɪ/)
