An acronym is a combination of letters that can be pronounced as a word. An initialism is an
unpronounceable combination of letters.
General
Avoid overwhelming your reader with acronyms and initialisms.
An acronym is an abbreviation that is formed by combining the first letter or
letters of several words. Acronyms are pronounced as words. Examples
include:
modem = modulator and demodulator
EPCOT = Experimental Prototype Community of Tomorrow
NATO = North Atlantic Treaty Organization
An initialism is an abbreviation that is formed by combining the initial letter
of each word in a multiword term. Initialisms are pronounced as separate
letters. Examples include:
CRT = cathode ray tube
GUI = graphical user interface
WFO = work for others
When using an acronym or initialism for the first time in text, enter the full
phrase in its expanded version followed by the abbreviated form in
parentheses. Example: Sandia National Laboratories (SNL). In a short
report, one expanded version is sufficient. However, in a lengthy report, you
may want to repeat the expanded version in a later section to refresh the
reader’s memory, followed by parentheses.
Plurals
Form the plural of an acronym or initialism by adding s, as in PMFs. Use
the apostrophe only when it may be confusing, as in Kd’s.
Using a or an
Acronyms: The indefinite article to be used with an acronym is determined
by the initial sound of the “word.” Examples: a FORTRAN program, or an
Ada programmer.
Initialisms: The indefinite article to be used is determined by the initial
sound of the initialism’s first letter. If the first letter has a vowel sound use
“an,” as in “an SNL employee.” If it has a consonant sound, use “a,” as in
“a WFO proposal.”
Capitalization
Capitalize acronyms; do not use periods. The only exceptions are those
acronyms that have become accepted as common nouns, which are written in
lower case. Examples: NASA, HUD, laser, scuba.
Initialisms may be either upper or lower case. In general, do not use periods
when they are in uppercase.
