What Does “Passerby” Mean?
A passerby is someone who is walking or moving past a place. The person is not staying there. They simply pass by.
Examples:
- A passerby helped the lost child.
- One passerby called the police.
- A friendly passerby gave us directions.
The word is often used in newspapers, stories, and everyday conversations.
Why Is the Plural “Passersby”?
This is where many learners become confused.
The word passerby has two parts:
- passer = a person who passes
- by = passing a place
When English makes this word plural, it changes passer into passers.
So:
- passer → passers
- passerby → passersby
The word by stays exactly the same.
Think of it like this:
One passer by a store.
Many passers by a store.
Over time, the words joined together to become passerby and passersby.
Why Is “Passerbyers” Wrong?
Some people think every singular word simply adds -s or -ers at the end.
That idea creates the incorrect word:
❌ passerbyers
This is not accepted in standard English.
Native speakers, dictionaries, teachers, and grammar books do not use passerbyers.
Always use:
- passerby
- passersby
Never use:
- passerbyers
