Forming and Using Plurals: A Guide for Key Stage 3 Students

Plurals are simply the way we talk about more than one of something. For example, when you have one book, it’s singular, but when you have two or more books, you use the plural form. Let’s break down the rules for forming plurals in English, along with examples and tips to make it easier.


1. Rule for Most Nouns: Add -s

The easiest way to make most nouns plural is to just add -s to the end of the word.

  • Examples:
  • one car → two cars
  • one tree → three trees
  • one book → five books

2. Nouns Ending in -s, -ch, -sh, -x, or -z: Add -es

If a noun ends in -s, -ch, -sh, -x, or -z, just adding -s would make it hard to pronounce, so we add -es instead.

  • Examples:
  • one bus → two buses
  • one fox → three foxes
  • one watch → four watches
  • one buzz → five buzzes

3. Nouns Ending in Consonant + y: Change -y to -ies

When a noun ends with a consonant followed by -y, we drop the -y and add -ies. A consonant is any letter that is not a vowel (a, e, i, o, u).

  • Examples:
  • one baby → two babies
  • one city → five cities
  • one puppy → four puppies

But, if a noun ends in a vowel + y, just add -s:

  • Examples:
  • one toy → two toys
  • one key → six keys

4. Nouns Ending in -f or -fe: Change to -ves

Some nouns that end in -f or -fe change the -f to -v and add -es when they become plural. This is because the sound of the word changes slightly from /f/ to /v/ in the plural form.

  • Examples:
  • one wolf → two wolves
  • one knife → three knives
  • one leaf → four leaves

However, not all nouns ending in -f or -fe follow this rule. Some just take -s:

  • Examples:
  • one chef → two chefs
  • one roof → five roofs
  • one belief → many beliefs

5. Nouns Ending in -o: Add -s or -es

For nouns ending in -o, you usually just add -s to make them plural.

  • Examples:
  • one piano → two pianos
  • one photo → three photos

But, there are some exceptions where you add -es:

  • Examples:
  • one tomato → two tomatoes
  • one potato → four potatoes
  • one hero → three heroes

Tip: Remember that tomatoes and potatoes always add -es.


6. Irregular Plurals

Some nouns don’t follow the usual rules and have their own special plural forms. These are called irregular plurals, and you need to memorize them.

  • Examples:
  • one child → two children
  • one man → three men
  • one woman → five women
  • one mouse → four mice
  • one foot → two feet

7. Nouns That Stay the Same

Some nouns don’t change at all in their plural forms. The word stays the same whether you’re talking about one or many.

  • Examples:
  • one sheep → two sheep
  • one fish → several fish
  • one deer → many deer

Tips & Tricks for Remembering Plurals

  1. For -f and -fe endings: If the sound changes from /f/ to /v/, use -ves (like leafleaves). If the sound stays the same, just add -s (like roofroofs).
  2. For -o endings: Remember the exceptions like tomato and potato that add -es. For others like piano, just add -s.
  3. Practice irregular plurals: These don’t follow the rules, so the more you use them, the easier they will become to remember.

Examples to Practice
