Sense: noun/3

'Supporter', 'advocate', 'backer', 'promoter', and 'endorser' all describe people on someone's side, but each has a different emphasis. A 'supporter' is the broadest term, covering anyone who agrees with or helps a person or a cause without requiring a public statement. An 'advocate' actively argues in favour of something, often publicly and with strong conviction. A 'backer' typically provides financial support for a project, candidate, or organisation. A 'promoter' works actively to increase the popularity or success of something through events, marketing, or personal appearances. An 'endorser' differs in that they give explicit, public approval — often a well-known figure whose name adds credibility. For example, a former president may be an endorser of a new education bill, while a wealthy donor is a backer of the campaign, and a teachers' union is a supporter of the policy.

Etymology

LatinAnglo-FrenchMiddle EnglishEnglish

The word 'endorser' is formed from the verb 'endorse' plus the agent suffix '-er', meaning 'a person who endorses'. The verb 'endorse' comes from Middle English 'endossen', borrowed from Anglo-French 'endosser' meaning 'to put on the back'. This is derived from Latin 'dorsum' meaning 'back'. The original financial sense — signing on the back of a cheque — gave the word its core meaning, which later expanded metaphorically to 'giving public support or approval'.
