Common Errors in English: Irregular Plurals

Don’t say: “I have three childrens.”

Say: “I have three children.”

Or: “I have three kids.”

The plural of “child” is “children” – because the word “children” is already plural, we don’t add “s.” Another possibility is to say “kids,” which is an alternative word for “children.”

Here are some more nouns with irregular plurals:

  • person / people
  • man / men
  • woman / women
  • stimulus / stimuli
  • analysis / analyses
  • thesis / theses
  • foot / feet
  • tooth / teeth
