Plural of Nouns worksheet with exercises for grammar practice.

Let’s solve this step by step.

We are working on plural nouns — that means turning singular words (one thing) into plural words (more than one thing).

There are three sections:

---

Section 1: Write the plural

We go word by word and apply standard plural rules:

- Most nouns → add -s
- Nouns ending in -ch, -sh, -x, -z, -o → often add -es
- Nouns ending in consonant + y → change y to i and add -es
- Some irregulars stay the same or change completely (like “child” → “children”, but we’ll check each)

Let’s do them:

1. Apple → Apples
2. Nose → Noses
3. Child → Children *(irregular)*
4. Knife → Knives *(f → ves)*
5. Piano → Pianos *(just add s — not all -o words take -es)*
6. Fish → Fish *(same for singular and plural)*
7. Party → Parties *(y → ies)*
8. Family → Families *(y → ies)*
9. Hamburger → Hamburgers
10. Vegetable → Vegetables
11. Sheep → Sheep *(same for singular and plural)*
12. Mouse → Mice *(irregular)*
13. Wife → Wives *(fe → ves)*
14. Bus → Buses *(ends in s → add es)*
15. Tooth → Teeth *(irregular)*
16. Sweet → Sweets
17. Foot → Feet *(irregular)*
18. Baby → Babies *(y → ies)*
19. Box → Boxes *(ends in x → add es)*
20. Dictionary → Dictionaries *(y → ies)*
21. Watch → Watches *(ends in ch → add es)*
22. Tiger → Tigers
23. Cherry → Cherries *(y → ies)*
24. Person → People *(irregular)*
25. Eye → Eyes
26. Wolf → Wolves *(f → ves)*
27. Party → Parties *(already did — same as #7)*
28. Cake → Cakes
29. Face → Faces
30. Egg → Eggs
31. Computer → Computers
32. Staff → Staff *(can be same for singular/plural when meaning group of workers; sometimes “staffs” if referring to multiple groups, but usually “staff” is acceptable as plural too — however, in school context, they may expect “staff” unchanged)*
→ Actually, let’s double-check: In most elementary contexts, “staff” is treated as both singular and plural (like “sheep”). So we’ll write Staff

Wait — correction: For consistency with typical grade-level expectations, “staff” as a collective noun often stays the same. But some curricula teach “staffs” for multiple groups. Since no context is given, and it's listed with other regular/irregular plurals, safest is to treat it like “sheep” — same form. However, looking at common usage in worksheets, many accept staff as plural. Let’s stick with Staff.

But wait — actually, let me verify: In modern English, “staff” can be pluralized as “staff” (collective) or “staffs” (multiple groups). Since this is a basic worksheet, and “sheep” and “fish” are already there as invariant plurals, likely “staff” is also expected to remain staff.

However, I recall that in many such worksheets, “staff” is sometimes written as “staffs”. To be safe, let’s check common textbook answers.

Actually, upon second thought — in most K–5 grammar resources, “staff” is taught as having the same form for singular and plural when referring to employees. Example: “The staff are here.” So we’ll put Staff.

BUT — let’s look again at the list: They have “sheep”, “fish” — which are clearly invariant. “Staff” is similar. So final answer: Staff

Wait — I think I made a mistake earlier. Let me recheck reliable source mentally: Merriam-Webster says “staff” can be pluralized as “staff” or “staffs”. In educational contexts for young students, they often use “staff” as plural. We’ll go with Staff.

Actually, let’s move on — maybe the teacher expects “staffs”? Hmm.

Looking at pattern: All others follow clear rules. “Staff” ends in ‘ff’ — not special. Maybe just add ‘s’? No — because “cliff” becomes “cliffs”, so why not “staffs”?

I think I overcomplicated. Let’s apply rule: If no special rule, add -s. “Staff” doesn’t end in s, x, z, ch, sh, o, or f/fe/y — so just add -s → Staffs

Yes! That makes sense. “Cliff” → “cliffs”, “roof” → “roofs”, so “staff” → “staffs”

Final decision: Staffs

(Many sources say both are correct, but for consistency with adding -s unless specified otherwise, we’ll use Staffs)

Actually, let me confirm with logic: The worksheet includes “knife” → “knives” (f→ves), “wife” → “wives” (fe→ves), so “staff” has double f — still follows f→ves? No — only single f or fe typically changes. Double f usually just adds s: e.g., “cliff” → “cliffs”, “puff” → “puffs”.

So “staff” → staffs

Okay, settled.

Continuing:

32. Staff → Staffs

Now Section 2: Rewrite sentences into plural

We need to change the subject and verb to match plural, and adjust any related words.

Original:
1. There is a child in front of the tree.
→ Plural: There are children in front of the trees.
*(“is” → “are”, “a child” → “children”, “tree” → “trees” — assuming more than one tree? Wait — original says “the tree” — could be one tree with multiple children. But sentence structure: “There is a child...” implies one child near one tree. When making plural, we should make everything plural where logical. Typically, we change “child” to “children”, and since “there is” becomes “there are”, and “tree” might stay singular if it’s the same tree, but often in these exercises, they pluralize all countable nouns. Let’s see example patterns.

Standard approach: Change subject to plural, adjust verb, and pluralize objects if they were singular and now imply multiple.

But “in front of the tree” — if we have multiple children, they could still be in front of one tree. However, in most workbook exercises, they pluralize all applicable nouns.

Check sentence 2: “I am your best friend.” → “We are your best friends.” — here “friend” becomes plural.

Similarly, sentence 3: “There is a pen under the book.” → “There are pens under the books.” — probably pluralizing both.

So let’s assume we pluralize all countable nouns that were singular.

Thus:

1. There is a child in front of the tree.
→ There are children in front of the trees.

But wait — is “tree” necessarily plural? Not really. But to match the exercise style, likely yes.

Alternatively, perhaps only the subject and its direct modifiers. Let’s look at sentence 4: “He has got an orange in his hand.” → “They have got oranges in their hands.” — here “hand” becomes “hands”.

So yes, they pluralize associated body parts/items.

So for #1: “child” → “children”, “tree” → “trees” (assuming multiple trees for multiple children? Or keep tree singular? Ambiguous.)

Actually, better to think: The phrase “in front of the tree” — if we have multiple children, they can still be in front of one tree. But in grammar exercises, they often pluralize all nouns for simplicity.

I recall standard answer for this type:
“There are children in front of the tree.” — keeping “tree” singular.

But let’s check online or common practice.

Upon reflection: In “There is a child in front of the tree,” changing to plural:
Subject: “a child” → “children”
Verb: “is” → “are”
Object/location: “the tree” — can remain singular because multiple children can be in front of one tree.

However, in many textbooks, they do pluralize it. Let’s see sentence 5: “She has got a child.” → “They have got children.” — no location, so simple.

Sentence 6: “My neighbor usually buys in this shopping centre.” → “My neighbors usually buy in these shopping centres.” — here “neighbor” → “neighbors”, “buys” → “buy”, “this” → “these”, “centre” → “centres”.

So they are pluralizing demonstratives and nouns.

Therefore, for #1: “the tree” should become “the trees” if we’re being consistent.

But “in front of the trees” might imply each child in front of different trees, which is odd.

Perhaps better to keep “tree” singular.

I think the intended answer is:
There are children in front of the tree.

Because the focus is on the subject “child” becoming “children”, and the location doesn't need to change.

Similarly, in sentence 3: “There is a pen under the book.” → “There are pens under the book.” — book can stay singular.

But in sentence 6, they changed “this shopping centre” to “these shopping centres”, so they are pluralizing the object.

This is inconsistent.

Let’s look for a pattern in the sentences provided.

Sentence 2: “I am your best friend.” → “We are your best friends.” — “friend” becomes plural.

Sentence 3: “There is a pen under the book.” → likely “There are pens under the books.” — pluralizing both.

Sentence 4: “He has got an orange in his hand.” → “They have got oranges in their hands.” — “hand” to “hands”.

So yes, they are pluralizing all countable nouns that were singular.

Therefore:

1. There is a child in front of the tree.
→ There are children in front of the trees.

Even if semantically odd, grammatically for the exercise, it's expected.

Similarly:

2. I am your best friend.
→ We are your best friends.

3. There is a pen under the book.
→ There are pens under the books.

4. He has got an orange in his hand.
→ They have got oranges in their hands.

5. She has got a child.
→ They have got children.

6. My neighbor usually buys in this shopping centre.
→ My neighbors usually buy in these shopping centres.

7. I don’t like this book.
→ We don’t like these books.

8. That is the best cake I’ve ever eaten.
→ Those are the best cakes I’ve ever eaten.

Note: “That” → “Those”, “cake” → “cakes”

Section 3: Complete with a, an, or nothing (zero article)

Rules:
- Use a before consonant sounds
- Use an before vowel sounds
- Use nothing for uncountable nouns, plural nouns, or general concepts

Sentences:

1. I don’t want ___ banana. I prefer chocolate ice-cream.
→ “banana” is singular countable, starts with consonant sound → a

2. Do you wear ___ orange or strawberry dress?
→ “orange” starts with vowel sound → an
But note: it’s “orange or strawberry dress” — so it’s asking about color, but “dress” is singular, so we need article before “orange” because it’s describing the dress.
Actually, the blank is before “orange”, so: “Do you wear ___ orange or strawberry dress?”
This is a bit tricky. It’s implying “an orange [dress] or a strawberry [dress]”, but since “strawberry” starts with consonant, it would be “a strawberry dress”, but the blank is only before “orange”.
In such cases, we use the article based on the first word after the blank.
“orange” starts with vowel sound → an

3. I’ve got ___ cat, ___ rat, ___ tortoise.
All singular countable, start with consonant sounds → a, a, a

4. ___ books are on the table.
“books” is plural → no article needed → nothing (or leave blank)

5. Here is ___ money.
“money” is uncountable → no article → nothing

6. My grandmother always eats ___ bananas after dinner.
“bananas” is plural → no article → nothing

7. My sister has got ___ new car.
“new car” — singular countable, “new” starts with consonant sound → a
