Educational worksheet on indefinite pronouns with interactive exercises and illustrations.

Let's solve this worksheet step by step. The task is to fill in the blanks with the correct indefinite pronouns (compounds of *some, any, no, every*) based on context and grammar rules.

We are given categories:

- People: someone, somebody, anyone, anybody, nobody, no one, everyone, everybody
- Things: something, anything, nothing, everything
- Places: somewhere, anywhere, nowhere, everywhere

Also:
- SOME → used in positive sentences and questions (offers/requests)
- ANY → used in negative sentences and questions
- NO → used in positive sentences with a negative meaning
- EVERY → used in positive and interrogative sentences

Let’s go through each sentence:

1. Jack was sad because ________ wanted to play with him.
→ Jack is sad → no one wanted to play.
→ Negative meaning → nobody / no one
✔ Nobody (or no one) — both are correct, but "nobody" is more common here.
➤ Nobody

2. I can smell ________ nasty in the bottom of the fridge.
→ Smelling something unpleasant → it's something (positive, real thing)
➤ something

3. Can I have ________ to eat, please?
→ Request → use something (positive offer/request)
➤ something

4. He wanted to see some tropical fish but he didn’t see ________.
→ He didn't see any → negative sentence → anything
➤ anything

5. ________ invited Tom to the party yesterday. He was very happy!
→ Someone did it → positive → Someone or Somebody
➤ Someone

6. Our teacher is very popular. ________ loves her!
→ Everyone loves her → positive → Everyone
➤ Everyone

7. Don’t tell ________! It’s a secret!
→ Don’t tell anyone → negative meaning in imperative → anyone
➤ anyone

8. He went bird-watching ________ in Italy.
→ Going to various places → everywhere
➤ everywhere

9. He can’t go ________ at the moment. He is contagious and he must stay at home.
→ Can’t go to any place → anywhere
➤ anywhere

10. He does ________ on time. He’s hopelessly disorganised.
→ Doesn’t do things on time → negative meaning → nothing
➤ nothing

11. She keeps ________ on her desk. She’s so untidy…
→ Clutter → has many things → everything or something?
But “keeps everything” implies all kinds of stuff → everything
➤ everything

12. My granddad can’t hear ________!
→ Can't hear anything → negative → anything
➤ anything

13. There was ________ on that island! He was alone.
→ No people → nobody
➤ nobody

14. The detective found some footprints ________ around the house.
→ Footprints in various places → everywhere
➤ everywhere

15. He has no job and ________ to live.
→ No money → nothing
➤ nothing

16. ________ hit Jim during the game.
→ Someone hit him → positive → Someone
➤ Someone

17. She buys ________ online.
→ Buys things → something or everything?
But “buys something” fits better — not necessarily everything.
But “she buys things online” → something
However, if it’s habitual, “everything” might be possible, but “something” is safer.
Actually, since she's shown buying multiple items, maybe everything?
But “buys everything online” means all her purchases — could be true.
But more likely: something → she buys *some* things online.
Wait — the image shows her buying various items → probably everything?
But the phrase is: “She buys ________ online.”
Without more context, “something” is neutral.
But if we assume she buys *all* her stuff online → everything
Looking at the cartoon: she’s sitting with shopping bags — seems like lots of things → possibly everything
But something is safer unless we know it’s all.
However, in such exercises, “everything” is often used for full extent.
Let’s reconsider: “She buys everything online” = all her purchases → possible.
But “She buys something online” = she buys some things → also possible.
Given the context, everything makes more sense as a complete answer.
But let’s check grammar: both are valid.
But since she’s shown with multiple bags, likely everything
➤ everything

Wait — actually, the word everything would mean *all* her purchases. But if she only buys some things online, it's not accurate.
But the image doesn’t show what she’s buying.
So safest: something
But let’s look again: the cartoon shows her with shopping bags, maybe implying she shops online for all her needs?
Still ambiguous.
However, something is more natural in everyday speech.
But in these types of worksheets, everything is often used when the person is doing it completely.
Alternatively, perhaps everything isn’t right — maybe some things? But we need one word.
We can only use the compound pronouns listed.
So options: something, anything, everything, nothing
Since she *does* buy things → something is best.
➤ something

18. Is there ________ who can tell a pirate tale?
→ Question asking if someone exists → use anyone (question)
➤ anyone

19. There’s ________ at the door.
→ Someone is at the door → positive → someone
➤ someone

20. There’s ________ to do so he can relax.
→ Nothing to do → he can relax → nothing
➤ nothing
