Initialism
An abbreviation formed from the first letters of a phrase, pronounced letter by letter rather than as a word.
Why it matters
Initialism is often confused with acronym; the distinction matters in style guides and technical writing.
Examples
- FBI, HTML, ATM
Best practices
- Spell initialisms with no periods in most modern style guides
- Reserve 'acronym' for cases pronounced as a word
