In English, nouns can be singular (one) or plural (more than one). To make most nouns plural, you simply add -s to the end. For example, one book torna-se two books. This change helps us know if we are talking about one thing or many things.

Sometimes, the ending changes a little more. For nouns ending in -s, -ss, -x, -ch, ou -sh, somamos -es. Por exemplo, one bus torna-se two buses. If a noun ends in a consonant plus -y, como city, we change the -y para -ies, so one city torna-se two cities. These rules are important for speaking and writing English correctly.

What are Singular and Plural Nouns?

Nouns are words for people, places, things, or ideas. In English, nouns have two main forms:

  • Singular: This means there is only one of something. For example, a cat, a house, a friend.
  • Plural: This means there are more than one of something. For example, cats, houses, friends.

We use singular nouns with a ou an. We use plural nouns with numbers like two ou three, or words like some ou many.

How Do We Make Nouns Plural?

Most nouns become plural by adding -s to the end. This is the most common rule.

  • bookbooks
  • tabletables
  • penpens

Some nouns have special rules for making them plural. These rules depend on the last letters of the word.

Nouns ending in -s, -ss, -x, -ch, -sh

If a noun ends with -s, -ss, -x, -ch, ou -sh, somamos -es to make it plural.

  • busbuses
  • glassglasses
  • boxboxes
  • matchmatches
  • brushbrushes

Nouns ending in a consonant + -y

If a noun ends with a consonant (like b, c, d, f, g, etc.) followed by -y, we change the -y para -i e acrescente -es.

  • citycities
  • babybabies
  • partyparties

But if a noun ends with a vowel (like a, e, i, o, u) followed by -y, we just add -s.

  • boyboys
  • daydays
  • toytoys

Erros comuns entre falantes de espanhol

Spanish speakers sometimes make mistakes with English plural nouns because the rules are different:

  • Forgetting -s: In Spanish, you often add -s ou -es, but sometimes you might forget it in English, especially for words that are similar. Always remember to add an ending for plural nouns in English.
    Incorreto: I have two book.
    Correto: I have two books.
  • Not using -es ou -ies: It's easy to just add -s to every word. But remember the special rules for words ending in -s, -ss, -x, -ch, -sh (add -es) and words ending in consonant + -y (change to -ies).
    Incorreto: I see two citys.
    Correto: I see two cities.
    Incorreto: He cleans the dishs.
    Correto: He cleans the dishes.

Perguntas frequentes

Why do we need singular and plural nouns?

We need singular and plural nouns to show if we are talking about one thing or many things. This helps us understand the quantity of what we are discussing, like one apple versus three apples.

How do I know if I should add -s, -es, or -ies?

Most nouns add -s. Se um substantivo terminar em -s, -ss, -x, -ch, ou -sh, add -es. If a noun ends in a consonant plus -y, change -y para -ies. If it ends in a vowel plus -y, just add -s.

Are there any nouns that do not follow these rules?

Yes, there are some irregular plural nouns in English, like man (singular) becoming men (plural). However, for Pre-A1 English, focus on the regular rules first. You will learn irregular plurals later.
