1. Most Common Plural Rule: Add ’s’ or ‘es’ When you want to make a word plural in English, the most common rule is to add ’s’ or ‘es’ to the singular form. For instance:
- cat → cats
- dog → dogs
- girl → girls
- car → cars
- family → families
However, there are exceptions, especially with words ending in ’s’, ‘sh’, ‘ch’, ‘x’, or ‘z’.
2. Words Ending in ’s’, ‘sh’, ‘ch’, ‘x’, or ‘z’ For words that end in these sounds, you typically add ‘es’ to form the plural:
- box → boxes
- wish → wishes
- church → churches
- bus → buses
- fix → fixes
But be cautious with ‘fixes’ as it’s the plural form of ‘fix,’ not ‘fixes.’
3. Words Ending in ‘y’ When a word ends in ‘y,’ you often change the ‘y’ to ‘ies’ to make it plural:
- baby → babies
- city → cities
- fly → flies
- spy → spies
- lady → ladies
Remember that if the word ends in a consonant followed by a ‘y,’ you typically just add ’s’:
- cry → cries
- crybaby → crybabies
4. Irregular Plurals Some words have irregular plurals that you just need to memorize:
- child → children
- man → men
- woman → women
- foot → feet
- tooth → teeth
5. Plurals of Numbers Numbers are often treated as singular in the plural form:

- brother-in-law → brothers-in-law (the second part is pluralized)
- son-in-law → sons-in-law (the second part is pluralized)
- good-for-nothing → good-for-nothings (the compound is treated as a single concept)
7. Plurals of Plurals The plural of a plural is usually just the word with an ’s’ added:
- boys → boys’ toys
- women → women’s clothing
8. Plurals of Letters and Symbols Letters and symbols can be pluralized in different ways:

- B → B’s (also for possessive, like ‘B’s are rare)
- X → X’s (for possessive, like ‘X’s are used in multiplication)
9. Plurals of Numbers Used as Nouns When numbers are used as nouns, they can take on a plural form:
