To make most nouns plural in English, we add -s to the end of the word. Por exemplo, cat torna-se cats. However, English has some special rules for other nouns. If a noun ends in -s, -ss, -x, -ch, ou -sh, we add -es, como bus para buses. If a noun ends in -y after a consonant, we change -y para -ies, for instance, baby torna-se babies. Some nouns are irregular and change completely, such as man para men. Understanding these rules helps you speak and write English clearly.

What Are Plural Nouns?

In English, nouns can be singular or plural. A singular noun means there is only one of something. A plural noun means there is more than one.

  • One book (singular)
  • Two books (plural)

It is important to use the correct form to show quantity.

How Do We Make Most Nouns Plural?

For most nouns in English, we simply add -s to the end of the word.

  • dogdogs
  • tabletables
  • carcars
  • flowerflowers

What About Nouns Ending in -s, -ss, -x, -ch, -sh?

When a noun ends with -s, -ss, -x, -ch, ou -sh, we add -es to make it plural. This makes the word easier to say.

  • busbuses
  • dressdresses
  • boxboxes
  • watchwatches
  • brushbrushes

Nouns Ending in -y?

If a noun ends in -y and the letter before -y is a consonant (like b, d, r, t), we change the -y para -i and add -es.

  • babybabies
  • citycities
  • partyparties

But if the letter before -y is a vowel (like a, e, i, o, u), we just add -s.

  • toytoys
  • daydays
