Sender

Sophie had been looking forward to getting another letter from the unknown sender.

They confused the names of the sender and the addressee.

A mailbag from a single sender addressed to one recipient, as the name suggests, is for delivering a bag of printed matter.

What a strange message! There is no sender and no recipients either.

Return to sender.

Return to the sender.

When Josefa received the letter, she got really happy. The sender was a classmate from school she hadn't heard from in years.

"Sir, there's a package for you." "Who's the sender?"

The receiver collects the electromagnetic waves and demodulates them, decoding the sender’s message.

Do you mean the sender or the recipient of the letter?
