Plurals: -s/-es

Definition / Explanation

Most English nouns make the plural by adding -s or -es. We use plural forms when we talk about more than one person, thing, or animal. Many nouns simply take -s, but some common spelling patterns use -es. Learning these regular plural forms is an important first step before irregular plurals.

Key Rules

  • Add -s to many nouns: cat -> cats, book -> books.
  • Add -es after s, ss, sh, ch, x, z: bus -> buses, box -> boxes.
  • Plural nouns often go with numbers: two bags, five students.
  • Use plural nouns with are, not is.
  • Do not add -s after a number if the noun is uncountable: two waters is usually wrong in basic grammar.

Examples

  • One cat, two cats.
  • One bus, three buses.
  • These books are new.
  • My sisters live in London.
  • There are two dishes on the table.

Common Mistakes

  • ❌ Two cat. -> ✅ Two cats.
  • ❌ Three boxs. -> ✅ Three boxes.
  • ❌ The students is here. -> ✅ The students are here.
