disproof
UK: dɪsˈpruːf | US: dɪsˈpruːf
n. evidence or argument that disproves something; refutation.
n. the act of proving something false.
disproof = dis<opposite> + proof<evidence>
- dis<opposite>: A prefix of Latin origin (via Old French) meaning "apart," "away," or "negation." Here, it reverses the meaning of "proof."
- proof<evidence>: From Old French preuve (evidence), derived from Latin probare (to test or prove). Retains its core meaning of "evidence supporting truth."
Etymology Origin:
The word "disproof" emerged in Late Middle English by combining the negating prefix dis- with proof, creating a term for evidence that contradicts or invalidates a claim. This mirrors the logical structure of many English words where dis- systematically negates the root (e.g., disagree, disallow). The root proof traces back to Latin probare, reflecting a historical focus on testing and verification.
