Indefinite Pronouns

English has a neat system of 12 indefinite pronouns built from just 4 groups — some-, any-, no-, and every- — combined with three endings for people, things, and places. Once you learn 1 core rule and 2 exceptions, you can use all twelve correctly.

Somebody = someone, anybody = anyone, nobody = no one, everybody = everyone. The pairs are fully interchangeable — there is no difference in meaning or formality. Use whichever you prefer.

The 1 Rule: Choose the group based on the polarity of the sentence — affirmative, negative, or question.

The 2 Exceptions: Offers/requests use some- even in questions, and any- in affirmative sentences can mean "it doesn't matter which".

Some-, Any-, and No- Compounds: The Basic Rules

The most important decision is which group to use. The rule depends on whether the sentence is affirmative, negative, or a question.

The Polarity Rule

Notice the two ways to express negation:

• negative verb + any-: "She didn't say anything."
• affirmative verb + no-: "She said nothing."

Both sentences mean exactly the same thing. The choice is stylistic — no- compounds often feel slightly more emphatic.

⚠️ The Double Negative Trap

This is the #1 mistake with indefinite pronouns. In standard English, you must never combine a negative verb with a no- compound.

Quick test: If your sentence already has don't, doesn't, didn't, can't, wasn't, won't, or any other negative word, use any- — never no-.

Adjectives Come After

Unlike regular nouns, indefinite pronouns take adjectives after them, not before:

Every- Compounds, Exceptions, and Special Patterns

Once you've mastered the basic some-/any-/no- rule, it's time to add the every- group and learn the important exceptions.

Every- Compounds: All People, Things, and Places

The every- group means all without exception:

Subject–Verb Agreement: Singular!

Despite referring to multiple people or things, all indefinite pronouns are grammatically singular and take a singular verb:

Exception 1: Some- in Offers and Requests

When you offer something or make a polite request, use some- even though the sentence is a question. This is because you expect or hope for a "yes" answer:

Quick test: Is the question a genuine "I don't know" question, or an offer/request? Genuine → any-. Offer/request → some-.

Exception 2: Any- in Affirmative Sentences = "It Doesn't Matter Which"

Sometimes any- appears in affirmative sentences — and that's perfectly correct. In this case, any- means "whichever / whoever / wherever — no restrictions":

Don't confuse everyone with anyone in affirmatives. "Everyone can come" = all people (every single person). "Anyone can come" = any person, no restrictions (it doesn't matter who). The difference is subtle but real.

The "Else" Pattern

After indefinite pronouns, use else (not other) to mean "additional" or "different":

Any vs No vs None: The B1 Challenge

At B1 level, the biggest challenge is choosing between any, no, and none. All three can express "zero", but they play different grammatical roles.

No vs None: Determiner vs Pronoun

Key rule: No must have a noun after it. None must NOT have a noun after it.

None of + Noun / Pronoun

When followed by of, always use none — never no:

• None of my friends have seen my dog.
• None of the answers were correct.
• None of them could help me.
• I asked everyone, but none of them knew.

Converting Between Structures

These pairs mean the same thing — choose whichever fits the sentence structure:

3-Step Conversion (not...any → no):

1. Find the negative word (don't, didn't, wasn't, etc.)
2. Remove it — make the verb affirmative
3. Change any- to no- (or any to no / none)

Example: "She didn't tell anyone." → Remove didn't → "She told..." → Change anyone to no one → "She told no one."

The Polarity Rule

The 2 Exceptions

1. Offers and requests → use some- even in questions: "Would you like something?"
2. "It doesn't matter which" → use any- in affirmatives: "Anyone can join."

3-Step Conversion: not...any → no

1. Find the negative word (don't, didn't, etc.)
2. Remove it — make the verb affirmative
3. Change any- to no-

No vs None

• no + noun: "There are no seats."
• none alone: "How many? None."
• none of + noun/pronoun: "None of them came."

Practice Tips

1. Check the verb first. Is it negative (with not/n't)? If yes, use any-. If the verb is positive and you need negation, use no-.
2. For questions, ask "Am I offering or genuinely asking?" Offers and requests use some-. Genuine questions use any-.
3. Remember the adjective rule. It's always something interesting, nothing new, anywhere quiet — the adjective follows the pronoun.
4. Practise the conversion. Take any sentence with not...any and rewrite it with no-, and vice versa. This builds flexibility and helps you avoid double negatives.
5. When in doubt between no and none, look for a noun. If a noun follows, use no. If no noun follows (or of follows), use none.
6. Explore other pronoun types. Once you're confident with indefinite pronouns, review Reflexive Pronouns (myself, yourself, themselves) — another essential pronoun category for A2–B1 learners.
