Introduction
Look around your classroom. You see one desk, but many desks. You have one pencil, but your friend has five pencils. When we talk about one thing, we use the singular form. When we talk about more than one thing, we use the plural form. In Class 3, we will learn all the important rules for changing singular nouns to plural nouns — including some tricky ones!
What is Singular and Plural?
Singular means one — one person, one animal, one place, or one thing.
Plural means more than one — two or more persons, animals, places, or things.
Singular: one mango, one diya, one child, one leaf
Plural: many mangoes, many diyas, many children, many leaves
Rule 1: Add -s (Most Nouns)
For most nouns, simply add -s at the end to make the plural form.
| Singular (One) | Plural (Many) | Singular (One) | Plural (Many) |
|---|---|---|---|
| book | books | pen | pens |
| cat | cats | dog | dogs |
| chair | chairs | table | tables |
| diya | diyas | roti | rotis |
| girl | girls | flower | flowers |
Example: Sita has one diya. Meena has ten diyas for Diwali.
Rule 2: Add -es (Nouns ending in s, sh, ch, x, o)
When a noun ends in -s, -ss, -sh, -ch, -x, or -o, add -es to make it plural.
| Singular (One) | Plural (Many) | Rule |
|---|---|---|
| bus | buses | ends in -s |
| glass | glasses | ends in -ss |
| brush | brushes | ends in -sh |
| bench | benches | ends in -ch |
| box | boxes | ends in -x |
| mango | mangoes | ends in -o |
| potato | potatoes | ends in -o |
| tomato | tomatoes | ends in -o |
Example: Arjun bought one mango. His mother bought a dozen mangoes from the market.
Rule 3: Change y to ies (Consonant + y)
If a noun ends in a consonant + y, change the y to i and add -es.
| Singular (One) | Plural (Many) |
|---|---|
| baby | babies |
| story | stories |
| city | cities |
| fly | flies |
| lady | ladies |
| army | armies |
But! If the word ends in a vowel + y, just add -s:
| Singular | Plural | Why? |
|---|---|---|
| boy | boys | vowel (o) + y |
| toy | toys | vowel (o) + y |
| key | keys | vowel (e) + y |
| monkey | monkeys | vowel (e) + y |
Rule 4: Change f or fe to ves
Some nouns ending in -f or -fe change to -ves in the plural form.
| Singular (One) | Plural (Many) |
|---|---|
| leaf | leaves |
| knife | knives |
| wife | wives |
| wolf | wolves |
| half | halves |
| shelf | shelves |
| life | lives |
| thief | thieves |
Rule 5: Irregular Plurals (Special Words)
Some nouns do not follow any rule. They change their spelling completely. We must learn these by heart!
| Singular (One) | Plural (Many) | Singular (One) | Plural (Many) |
|---|---|---|---|
| child | children | foot | feet |
| man | men | woman | women |
| tooth | teeth | goose | geese |
| mouse | mice | ox | oxen |
| person | people | cactus | cacti |
Example: One child is reading. Many children are playing in the park.
Example: The man is walking. The men are working in the field.
Words That Stay the Same (No Change)
Some nouns have the same form for both singular and plural.
| Singular | Plural |
|---|---|
| one sheep | many sheep |
| one deer | many deer |
| one fish | many fish |
| one aircraft | many aircraft |
