Plural Rules

  • A plural word represents more than one of something.

    –s, –es Rules

    ’s Rules
  • We add ’s when making letters plural.

    • example:  I got all A’s.
  • We add ’s when creating the plural of a word that refers to itself.

    Acronym Rules
  • Acronyms become plural by adding an s.
    • examples:  URLs, BRBs, RFPs, PMs, BFs, GFs
  • Acronyms ending with –s need ’s to be plural.
