Acronym Generator (and Backronym Maker)
Turn phrases into acronyms (National Aeronautics and Space Administration → NASA) with dotted and lower-case versions, or invent backronyms from themed word lists.
Hyphenated words count as separate words (Self-Contained → S C). Check that a new acronym does not already mean something you would rather avoid.
| Phrase | Acronym | Dotted | Every word | First two letters |
|---|---|---|---|---|
| National Aeronautics and Space Administration | NASA | N.A.S.A. | NAASA | NaAeSpAd |
| Portable Network Graphics | PNG | P.N.G. | PNG | PoNeGr |
| as soon as possible | ASAP | A.S.A.P. | ASAP | AsSoAsPo |
| Self-Contained Underwater Breathing Apparatus | SCUBA | S.C.U.B.A. | SCUBA | SeCoUnBrAp |
Turn a long name into a short acronym, or do the reverse and invent a phrase whose initials spell a word you already like. Acronym mode takes the first letter of each word, leaving out small words such as and, of and the the way most organisations do (National Aeronautics and Space Administration → NASA), and shows dotted, lower-case, every-word and first-two-letter versions. Backronym mode fills each letter of a word like HOPE or TEAM with positive, business or fun words.
How to use this tool
- Type one phrase per line (or a single word for a backronym).
- Choose acronyms or backronyms.
- For acronyms, choose which small words to leave out and the style; for backronyms, choose a theme and how many ideas.
- Copy the result; change the variation number for new backronym ideas.
Formula
Acronym = first letter of each word that is not on the skip list, joined and capitalised
Words are runs of letters and digits, so hyphens and slashes separate words (Self-Contained Underwater Breathing Apparatus → SCUBA) and an apostrophe stays inside a word. Real acronyms are inconsistent about small words: NASA drops “and”, but ASAP and FYI keep every word, so you can choose. The first-two-letters style gives a pronounceable code such as NaAeSpAd. Backronym words come from built-in lists of about five words per letter in each theme, chosen with a seeded random generator.
Example
The four sample phrases give NASA, PNG, ASAP and SCUBA. NASA leaves out “and”, while “as soon as possible” keeps all four words because “as” is not a skipped word. As a backronym, HOPE with positive words gives ideas such as “Hopeful Optimistic Patient Elegant”, and a new variation number shuffles the picks.
Frequently asked questions
What is the difference between an acronym and an initialism?
Strictly, an acronym is pronounced as a word (NASA, SCUBA) and an initialism is spelled out letter by letter (FBI, PNG). In everyday use both are called acronyms.
What is a backronym?
A phrase invented to fit an existing word, such as a team or project name chosen first, with words found later to match each letter.
Should I use periods (N.A.S.A.)?
Most style guides, including AP and Chicago, now write acronyms without periods. Periods are still common in some initialisms such as U.S. in American English.
