The word "endorsement" originates from the Old French endosser (to put on the back), derived from Latin indorsare (in- "on" + dorsum "back"). Historically, signing a document on its back symbolized approval or transfer of rights, evolving into broader meanings of public support or formal validation. The suffix -ment (from Latin -mentum) nominalizes the action, creating the modern sense of "official approval."
