What are Indefinite Pronouns?

Indefinite pronouns do not point to a specific person, thing, or place. They are general.

They are very useful when you don’t know exactly who or what you are talking about, or when it’s not important to be specific.

• For people, we use -one 或 -body （例如，, someone, anyone).
• For things, we use -thing （例如，, something, anything).
• For places, we use -where （例如，, somewhere, anywhere).

When Do We Use 'Some-' Words?

We use indefinite pronouns with some- (like someone, something, somewhere) mainly in positive sentences.

• 使用 someone 或 somebody for an unknown person.
• 使用 something for an unknown thing.
• 使用 somewhere for an unknown place.

我们还使用 some- words in questions when we expect a 'yes' answer, or when we are making an offer or a request.

When Do We Use 'Any-' Words?

We use indefinite pronouns with any- (like anyone, anything, anywhere) in questions and negative sentences.

• 使用 anyone 或 anybody in questions or negative sentences about people.
• 使用 anything in questions or negative sentences about things.
• 使用 anywhere in questions or negative sentences about places.

有时，, any- words can also be used in positive sentences to mean 'it doesn't matter who/what/where'.

When Do We Use 'No-' Words?

Indefinite pronouns with no- (like no one, nobody, nothing, nowhere) mean 'zero' or 'not any'.

It is important to use a positive verb with no- words. This is because the no- word itself makes the sentence negative.

• No one 和 nobody mean 'not a single person'.
• Nothing means 'not a single thing'.
• Nowhere means 'not a single place'.

When Do We Use 'Every-' Words?

Indefinite pronouns with every- (like everyone, everybody, everything, everywhere) mean 'all' or 'all people/things/places'.

• Everyone 和 everybody mean 'all people'.
• Everything means 'all things'.
• Everywhere means 'all places'.

Remember that even though every- words refer to many people or things, they always take a singular verb.

示例

• I heard something strange outside.
• Is there anyone home?
• Nobody came to the party.
• Everything is ready for the trip.
• Would you like something to drink?
• I can't find my keys anywhere.
• Everyone needs a break sometimes.
• There's somebody at the door.

西班牙语母语者常犯的错误

Spanish speakers sometimes make mistakes with indefinite pronouns, especially with negative sentences.

• Double Negatives: In Spanish, you can say 'no tengo nada' (I don't have nothing). But in English, you cannot use two negative words together. You must say I don't have anything 或 I have nothing. You cannot say I don't have nothing.
• Verb Agreement with 'Every-' words: 请记住这一点 everyone, everybody, ， 和 everything always take a singular verb. For example, it's Everyone is happy, 而不是 Everyone are happy.
• Using 'some-' in questions: Only use some- words in questions when you expect a 'yes' answer or are making an offer/request. For general questions, use any- words. For example, Do you have anything to say? (general question) vs. Would you like something to eat? (offer).

我们使用 someone in positive sentences and in questions where we expect a 'yes' answer or are making an offer. We use anyone in questions and negative sentences.

No, you cannot. Nobody already makes the sentence negative. For example, say Nobody came, 而不是 Nobody didn't come.
