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
