This is a complete guide for learners, writers, and anyone curious about this abbreviation. You will learn the meaning, origin, how to use it, common mistakes, and examples updated for 2026 language use.
What Does sb Mean?
In simple words:
“sb” means “somebody” or “someone.”
It is a short form used in dictionaries and sometimes in notes or chat to save space or time.
- sb = somebody = someone
- It refers to a person, but we do not know who exactly.
Example:
- “Tell sb to wait outside.”
This means “Tell somebody (one person) to wait outside.”
Here sb stands for an unknown or general person.
Where sb Comes From (Origin & History)
The abbreviation sb is not modern slang. Instead, it comes from dictionary conventions.
History in English Learning:
- English learners use sb in dictionaries to show that a verb or adjective can be used with a person.
- For example, dictionaries use sb in phrases like:
- sb + verb
- be friends with sb
- Teachers and learners adopted sb to make grammar teaching simpler.
Why sb Was Created
In older printed dictionaries:
- There was limited space.
- Authors needed a short way to refer to “somebody” or “someone.”
- So they used two letters instead of whole words.
This is why you see sb especially in dictionary examples, textbooks, and grammar books.
How sb is Used Today
Though sb started in dictionaries, you can see it in:
- Notes
- Grammar exercises
- Language apps
- Online explanations
- Teacher handouts
But remember:
- We do not use sb in formal writing.
- We do not use sb in everyday chat unless the other person understands it.

Simple Explanation for Beginners
Imagine you want to write:
Tell someone to come here.

Tell sb to come here.

This is similar to other grammar abbreviations like:
- sth = something
- sbd = somebody (less common)
- smbd = somebody (rarely used)
But sb remains the most widely used in dictionaries.
