What does disproval mean?
Disproval is a formal noun for the act of showing that a claim, assertion, or theory is false or unfounded. It can also denote the condition of being refuted and, in less technical use, may express strong opposition to a proposal or course of action. The word is less common than its near neighbour disapproval, but it is especially apt in discussions of evidence, reasoning, and formal challenge: evidence may lead to the disproval of a hypothesis, while a proposal may meet with disproval. Disproval has a somewhat technical or literary tone, yet it remains plain English rather than jargon. Learning it clarifies an important distinction: disliking a conclusion is not the same as demonstrating that it is wrong. Although disproval is most often used in its evidentiary sense, its broader implication of rejection gives it a firm, decisive character.

Disproval is approval turned inside out—and it implies not merely dislike, but a case against.

Where does disproval come from?
The word is an English formation from disprove plus the suffix -al, denoting the act of disproving. Disprove was borrowed through Old French from Latin elements meaning “not” and “to test or approve,” with the same Latin root underlying approve and proof. Its derivatives consequently range from approving a proposition to demonstrating that it is false.
How disproval is actually used
It has a formal, somewhat literary or technical register and is much less common than disapproval. It is especially appropriate when a claim is challenged on evidentiary or argumentative grounds.
