Usage: Use "signed" as an adjective to describe documents or items that bear someone's written name, such as a signed contract or signed photo. This form is often confused with the past tense verb "sign," but it functions grammatically only when modifying another noun rather than acting alone in a sentence.
Derived from Old French signer via Latin signare, it originally meant to make or put a mark as a signature. The past participle form retains this sense of authenticating a document through one's own sign.
