Sense: adverb/1
All five words describe language or arguments that lead others to accept a position, but they emphasise different aspects. Convincingly is the broadest — it simply means the listener is brought to believe, whether through logic, emotion, or evidence. Persuasively focuses on the speaker's skill in moving someone to agree or take action, often relying on emotional appeal. Compellingly suggests an irresistible quality — the argument demands attention and seems impossible to reject. Plausibly is weaker: it means the argument seems reasonable on the surface but may not be actually correct. Cogently is the most intellectual — it describes arguments that are logically clear, well-structured, and internally consistent. For example: 'She argued convincingly that the policy was flawed' (general belief). 'He presented the case cogently in court' (logical structure in a formal setting). 'The theory seemed implausible at first, yet the professor explained it so compellingly that the committee voted to fund the research.'
Etymology
Formed from convincing (the present participle of convince) plus the adverb-forming suffix -ly. The root verb convince comes from Latin convincere, a combination of the intensive prefix com- and vincere meaning 'to conquer'. So the original sense was 'to conquer thoroughly' — a meaning that later shifted from physical victory to mental persuasion.
