Etymology

The word "sender" combines the verb "send," derived from Old English sendan (meaning "to dispatch or cause to go"), with the agentive suffix "-er," which indicates "one who performs an action." This structure follows a common pattern in English where verbs are converted into nouns denoting actors (e.g., "teacher," "runner"). The term has retained its core meaning since Middle English, later expanding to include technical contexts like data transmission.

Examples
  1. The sender forgot to include a return address on the package.

  2. Email systems identify the sender in the "From" field.

  3. The message was delayed because the sender’s server was down.

  4. As the sender of the complaint, she expected a prompt response.

  5. The wireless sender transmits signals to the receiver.
