Plural Nouns

1 min
A1

Add -s to most nouns to make them plural (cat → cats), -es after s/x/ch/sh/o (box → boxes), change y to ies after a consonant (baby → babies), and memorize irregular plurals like man → men — some nouns like sheep don't change at all, and uncountable nouns like information have no plural form.

How do you make a plural noun?

Most nouns just add -s: cat → cats, book → books. Nouns ending in s, x, ch, sh, or o usually add -es instead: box → boxes, watch → watches, potato → potatoes. Nouns ending in a consonant + y change the y to i and add -es: baby → babies, city → cities.

What are irregular plurals?

Irregular plurals don't follow the -s pattern at all — they change form completely and have to be memorized: man → men, woman → women, child → children, foot → feet, tooth → teeth, mouse → mice, person → people.

Which nouns have no plural form?

Uncountable nouns like information, advice, furniture, and luggage have no plural form at all — you can't say "informations" or "advices." A few countable nouns also stay the same in singular and plural: sheep → sheep, fish → fish, deer → deer.

Common Mistakes

  • Forgetting -es for words ending in s/x/ch/sh: "boxs" should be "boxes".
  • Using -s with irregular plurals: "childs" should be "children", "mans" should be "men".
  • Adding -s to uncountable nouns: "informations", "advices" — these don't have plurals.

Tips

  • Common irregulars to memorize: man→men, woman→women, child→children, foot→feet, tooth→teeth, mouse→mice, person→people.
  • Words ending in -f / -fe often change to -ves: leaf→leaves, knife→knives, life→lives.

Advanced Notes

English plural spelling has more exceptions than the rule: alongside the standard -s, learners must navigate -es (boxes), vowel changes (foot→feet), zero plurals (sheep, fish, deer), and Latin/Greek survivals (criterion→criteria, datum→data). Uncountable nouns are a related trap — "information", "advice", "furniture", and "luggage" have no plural form at all. Native speakers occasionally misuse "datas" or "criterias" too, so learners are in good company.

FAQ

Do you say "boxs" or "boxes"?

Boxes — words ending in s, x, ch, or sh add -es, not just -s.

Is it "childs" or "children"?

Children — child is an irregular plural, like man → men and mans is also wrong.

Can you say "informations" or "advices"?

No — information and advice are uncountable nouns with no plural form at all. Just say "information" or "advice," no matter the amount.

Do plural nouns need "the"?

Only when the plural noun is specific and known: "The dogs next door bark all night." For a general statement, use no article: "Dogs bark."

Is it "much books" or "many books"?

Many books — many goes with countable plural nouns like books, while much goes with uncountable nouns like water.
