## Definition

describing something that is so clear or strong that you cannot argue against it. You use this when a fact or proof is impossible to deny.

For teachers: impossible to deny or disprove; providing a level of evidence that leaves no room for doubt. Often used in legal, scientific, or logical contexts to describe absolute proof.

## Examples

- The DNA evidence was irrefutable and led to a conviction.
- The witness provided an irrefutable timeline of events that contradicted the suspect's story.
- While the initial data was promising, the researchers needed to find an irrefutable link between the two variables before they could publish their findings in a peer-reviewed journal.
