signed

The word 'signed' is built upon the verb 'sign', which entered English via Old French from Latin signare (to mark), a derivative of signum. The core concept of signum in Latin was a distinctive mark, seal, or signal used for identification, authorization, or communication. The addition of the participial suffix '-ed', common in Germanic languages including Old English, transforms the action into a descriptive state. Thus, 'signed' logically denotes the condition of an object—be it a document, artwork, or digital data—that bears the authenticating mark or formal approval of its originator.

Structure: sign (mark) + ed (adjective suffix) - sign: From Latin signum (mark, token, indication). Functions as the core root conveying the concept of a distinctive mark or gesture. - ed: From Old English -ed, -od, -ad (past participle ending). Functions as a suffix forming adjectives from verbs, indicating a state or condition resulting from the action (having been signed).
