IPA: /dɪsˈpruːf/
KK: /dɪsˈpruf/
Evidence or argument that shows something is not true or correct.
The scientist presented a disproof of the previous theory, showing it was flawed.
Disproof → It is formed from "dis-" (meaning apart or away) and "proof" (from Old French *proef*, meaning to test or to prove). The word "disproof" refers to evidence that takes away or negates a claim or assertion, effectively proving it false.
Think of 'dis-' meaning 'apart' and 'proof' meaning 'to test' — so disproof is evidence that takes away the validity of a claim.
