The Origin of Signer or Signor
Signer:
The word “signer” comes from the verb “to sign,” which originates from Latin signare, meaning “to mark or seal.” In English, it has been used since the 16th century to refer specifically to a person who signs a document, check, or agreement.
Signor:
“Signor” is borrowed from Italian, where it is a respectful title similar to “Mister” in English. It comes from Latin senior, meaning “older” or “respected man.” In Italian culture, it is used before a man’s surname or full name.
