Possessive Nouns by adding (s) or () - Worksheet Digital - Free Printable

Let’s go through each sentence one by one. We need to show possession — meaning, who or what something belongs to.

We use:
- ’s for singular nouns (like Danny, princess, Iris, Lim, king, Mary, bird)
- ’ for plural nouns that already end in “s” (like wolves, men, babies, birds)

Wait — let’s double-check the rules:

✔ Singular noun → add ’s
Example: Danny → Danny’s aunt

✔ Plural noun ending in “s” → add just ’
Example: wolves → wolves’ teeth

✔ Irregular plural (doesn’t end in “s”) → add ’s
Example: men → men’s bags
babies → babies’ mothers? Wait — “babies” ends in “s”, so it’s plural → babies’ mothers

Actually, “babies” is plural and ends in “s”, so we use ’ after the s → babies’

Same with “birds” → birds’ feathers

Now let’s fix each sentence:

1. The wolves teeth → wolves is plural → wolves’ teeth
2. Danny aunt → Danny is singular → Danny’s aunt
3. princess skin → princess is singular → princess’s skin (or princess’ — both are okay, but usually we add ’s even if it ends in s for singular)
→ Let’s use princess’s to be clear
4. Iris father → Iris is singular → Iris’s father
5. Lims car → Lim is a name, probably singular → Lim’s car (unless “Lims” is meant to be plural family name — but context suggests singular owner)
→ Actually, “the Lims” might mean the Lim family → then it’s plural → Lims’ car
But looking at other sentences like “Danny”, “Iris”, “Mary” — they’re all singular people. So likely “Lim” is singular → Lim’s car
However, the word is written as “Lims” — which could be a typo or meant to be plural. In many worksheets, “the Lims” means the Lim family → plural → Lims’ car
Let’s check common usage: “the Smiths’ house” → plural family → Smiths’
So here: “the Lims car” → should be Lims’ car
6. king wife → king is singular → king’s wife
7. men bags → men is irregular plural → men’s bags
8. babies mothers → babies is plural ending in s → babies’ mothers
9. Mary room → Mary is singular → Mary’s room
10. birds feathers → birds is plural ending in s → birds’ feathers

Let me verify #5 again: “That is the Lims car.”
If “Lims” is meant to be the family name (like “the Joneses”), then it’s plural → Lims’ car
But sometimes names are treated differently. Since it says “the Lims”, it’s likely referring to the family → plural → Lims’ car

Also #3: “princess” — some style guides say if a singular noun ends in “s”, you can use just ’, but most school worksheets teach to add ’s for clarity. I’ll use princess’s.

Similarly, #4: Iris’s — same rule.

Okay, final versions:

1. The wolves’ teeth are very sharp.
2. She is Danny’s aunt.
3. The princess’s skin is very smooth.
4. I know Iris’s father very well.
5. That is the Lims’ car.
6. The queen is the king’s wife.
7. Those men’s bags are under the table.
8. The babies’ mothers are here to see them.
9. Mary’s room is on the left. *(Note: original said “Mary room in on the left” — probably typo, should be “Mary’s room is on the left”)*
10. The birds’ feathers are very colourful.

Wait — #9 original: “Mary room in on the left.” — that seems like a typo. Probably meant “Mary’s room is on the left.” We’ll correct that in our answer since we’re rewriting for possession and grammar.

Final Answer:
1. The wolves’ teeth are very sharp.
2. She is Danny’s aunt.
3. The princess’s skin is very smooth.
4. I know Iris’s father very well.
5. That is the Lims’ car.
6. The queen is the king’s wife.
7. Those men’s bags are under the table.
8. The babies’ mothers are here to see them.
9. Mary’s room is on the left.
10. The birds’ feathers are very colourful.
