What does endorser mean?
An endorser is a person who gives public approval or support to someone or something — a product, a political candidate, a cause, or an idea. The word appears most often in commercial and promotional contexts, where companies pay celebrities or respected figures to serve as endorsers of their brands, lending credibility and visibility through association. It also has a precise legal meaning in finance: the endorser is the party who signs the back of a cheque or other negotiable instrument, thereby transferring rights to it and often assuming liability if the payment fails. The term derives from the verb 'endorse', which traces back to the Latin 'dorsum', meaning 'back', reflecting the original practice of writing on the reverse side of a document. Endorsement by trusted figures is a cornerstone of modern advertising and political campaigning, making 'endorser' a useful word for discussing influence, persuasion, and trust in public life.

Etymology of endorser
Endorser derives from the verb 'endorse', which entered English in the late Middle Ages from Old French 'endosser', meaning literally 'to put on one's back' or 'to write on the back (of a document)'. The Old French word comes from Vulgar Latin 'indorsare', formed from Latin 'in-' ('upon') plus 'dorsum' ('back'). Cognates include the anatomical adjective 'dorsal'. The agent-noun form 'endorser' developed naturally alongside the verb, with 'endorsement' appearing slightly later as the noun for the act itself.
