Key Facts

Some nouns have the exact same spelling for both singular and plural. Examples include: Sheep, Deer, Fish, Aircraft, and Series.

Basic Rules for Changing Number

  1. Add '-s': Most nouns just take an 's' (Book -> Books, Cat -> Cats).
  2. Add '-es': Nouns ending in -s, -ss, -sh, -ch, -x, or -o take 'es' (Bus -> Buses, Box -> Boxes, Potato -> Potatoes).
  3. Words ending in '-y':
    • If preceded by a consonant, change 'y' to 'i' and add 'es' (Baby -> Babies).
    • If preceded by a vowel, just add 's' (Toy -> Toys).
  4. Words ending in '-f' or '-fe': Change 'f' to 'v' and add 'es' (Leaf -> Leaves, Knife -> Knives).

Irregular Plurals (Must Memorize)

Some words completely change their spelling:

  • Man -> Men
  • Woman -> Women
  • Child -> Children
  • Tooth -> Teeth
  • Foot -> Feet
  • Mouse -> Mice
  • Person -> People

Don't Forget the Verbs and Pronouns!

When you change the noun to plural, you MUST change the verbs and articles in the sentence.

  • 'is' / 'was' / 'has' becomes 'are' / 'were' / 'have'.
  • Drop the articles 'a' and 'an' (e.g., 'a cat' becomes 'cats').
  • 'This/That' becomes 'These/Those'.
