Synonym discussion

Sense: verb/1

All five words describe being on the favourable side of an idea, but they differ sharply in intensity and visibility. 'Support' is the broadest and weakest — it can be private and silent ('I support recycling'). 'Endorse' is short, public, and often official: a celebrity endorses a product, a newspaper endorses a candidate. 'Promote' adds active effort to spread acceptance, often through marketing or publicity, and is common in commercial contexts. 'Advocate' is more intellectual: you build an argument and speak up for an idea in public discussion, typical of writers, politicians, and experts. 'Champion' is the strongest, suggesting long-term, almost personal devotion to a cause. Compare: 'I support equal pay' (private opinion) vs 'She advocates equal pay in her weekly column' (public argument) vs 'He has championed equal pay for thirty years' (a defining life cause).

Etymology

LatinOld FrenchMiddle EnglishEnglish

From Latin 'advocatus', meaning 'one called to help', based on 'ad-' (to) plus 'vocare' (to call). It originally described someone called in to give legal aid to another in a Roman court. The word entered English through Old French in the fourteenth century, first as the noun (the courtroom helper), and only several centuries later as the verb (to publicly support an idea). The shared idea across all senses is the same: using your voice on someone's or something's behalf.
