## Definition

the person or organization that sends something, such as a letter, an email, or a package.

For teachers: the person, entity, or device from which a message or object originates. Often used in contrast with 'recipient' or 'receiver'.

## Examples

- The sender forgot to include their return address.
- If you receive an email from an unknown sender, you should avoid clicking on any links inside it.
- The protocol ensures that the identity of the sender is verified before the server accepts the incoming data packet, preventing unauthorized access to the network.

## Usage notes

- Commonly paired with 'of' to specify the item sent, such as 'the sender of the letter'.
