Plurals Nouns, add -ies

How to make nouns plural when they end in “y”?
Remember the rule:

• Consonant + y: Change the “y” to “-ies” (e.g., baby → babies).
• Vowel + y: Add “-s” (e.g., boy → boys).

This is a very consistent rule in English, so mastering it will significantly improve your grammar and spelling.

Examples of Consonant + y = -ies:
baby → babies
city → cities
country → countries
duty → duties
family → families
fly → flies
lady → ladies
party → parties

Examples of Vowel + y = -s:
boy → boys
day → days
key → keys
toy → toys
way → ways

The following diagram shows some examples of changing singular nouns ending in “y” into plural nouns. Scroll down the page for more examples.

 

Rules for forming plural of nouns
The most common way to form the plural of a noun is by adding “-s” to the end.
cat → cats
dog → dogs
book → books
Make plural nouns by adding s

Words ending in -s, -ss, -sh, -ch, -x, or -z: Add “-es” to form the plural.
This is because adding just “-s” would make the word difficult to pronounce.
bus → buses
dress → dresses
Make plural nouns by adding es

Words ending in consonant + -y: Change the “y” to “-ies”.
baby → babies
story → stories
Words ending in vowel + -y: Simply add “-s”.
boy → boys
day → days

Words ending in -f or -fe: In many cases, change the “f” or “fe” to “-ves”. However, some words just add “-s”.
leaf → leaves
chief → chiefs

Irregular Plurals:
Some nouns have irregular plural forms that don’t follow any of the above rules. These must be memorized.
man → men
child → children
foot → feet
ox → oxen
Nouns with the Same Singular and Plural Form:
Some nouns have the same form in both singular and plural.
