Someone vs. Somebody – Differences, Usage, Examples

Someone and somebody are two words that mean almost the same thing. Both are used when we don’t know who the person is. We use them when we are talking about a person, but we do not name them. These words are called indefinite pronouns.

They are both correct, but sometimes one fits better than the other. “Someone” sounds a little more formal, and “somebody” sounds more casual. In this guide, you will learn the differences, how to use them, many examples, and simple tips to help you choose the right word every time.

Differences Between Someone and Somebody

What do “someone” and “somebody” mean?

Someone and somebody are indefinite pronouns. That means they are used when we talk about a person, but we do not say who the person is.

Both words mean “an unknown person” or “a person we are not naming.”

Examples:

• “Someone is knocking at the door.”
• “Somebody left their phone here.”

Both sentences mean the same thing. The exact person is not known or not named.

How are they used in grammar?

They are singular.

• They work as subjects or objects in a sentence.
• They are followed by singular verbs.

Examples:

• “Someone is calling.” (subject)
• “Did you see somebody?” (object)

What is the difference in tone or formality?

While both mean the same thing, there is a tiny difference in tone:

• Someone is a bit more formal.
• Somebody is a bit more informal or casual.

Example:

• Formal: “Someone must attend the meeting.”
• Informal: “Somebody forgot their backpack.”

In writing or serious speech, people often choose someone.
In everyday talk, somebody sounds more natural.

Why do people confuse them?

People confuse these two because:

• They mean the same thing.
• They are used in similar sentences.

Many teachers and books say they are interchangeable.

And that’s true in most cases, you can use either one.
But knowing the small tone difference helps you sound more natural in different situations.

Quick Trick to Remember

“Someone” = Formal one

“Somebody” = Casual body
