Usage Notes

  • Plural: necessary conditions
  • Necessary condition is related to sufficient condition, which is a condition that, if present, guarantees an effect will occur.
  • Necessary conditions are not always “sufficient“. For example, an individual with ice cream can eat a bowl of ice cream if they have a bowl, but you can still eat ice cream without a bowl. Additionally, to eat a bowl of soup, it is not necessary or sufficient to have ice cream. Finally, it is both necessary and sufficient to have both a bowl and ice cream to eat a bowl of ice cream.
  • Also called necessary cause.
