A person who advocates for or supports a particular cause, theory, or proposal.
From Latin proponentem, present participle of proponere meaning 'to put forth, propose.' Formed from pro- (forward) + ponere (to place), literally meaning 'one who places forward' an idea or argument.
The word proponent carries more weight than simple 'supporter'—it implies active advocacy and reasoned argument rather than passive agreement. In academic and legal contexts, proponents are expected to present evidence and defend their positions intellectually.
