convincingly

Convincingly is an adverb derived from the adjective convincing, which describes something that leads others to be persuaded or believe a claim, argument, or narrative. As an adverb, convincingly modifies verbs and clauses, indicating the manner in which something is presented or argued. The core idea is that the proposition is supported by evidence, reasoning, or credibility that reduces skepticism.

Etymology: from the verb convince, from Latin convincere (con- 'with' + vincere 'to conquer'), entered English in Middle English through Old French. The adjective convincing appeared by the 15th century, and convincingly as an adverb formed by adding -ly.

Usage: Convincingly is commonly used to describe the effectiveness of argumentation, presentation, testimony, or demonstration. It often appears in academic, legal, journalistic, or evaluative writing. It contrasts with believably, which emphasizes the perceived credibility of a claim, rather than the force of the argument. It can be contrasted with persuasively, which emphasizes rhetorical skill; however, the two adverbs can overlap.

Examples: "The witness presented the timeline convincingly, leaving the jurors with little doubt." "The report argued convincingly that the policy would reduce emissions." "Although the theory is complex, the model is convincingly simple in its predictive power."
