verbC1GRESATGMATLSAT
FormalLegal

To confirm or give support to a statement, theory, or finding.

It implies adding new evidence that aligns with existing evidence, making the whole case stronger.

The story behind the word. The root 'robur' means 'oak' or 'strength' (the same root as 'robust'). To corroborate is to 'strengthen together'—like adding more oak beams to a structure to make it unshakeable.

Word relationships

  • substantiate: Substantiate means to provide the initial evidence for a claim; corroborate means to provide additional evidence that supports what is already there.
  • contradict: Contradict means to provide evidence that goes directly against a claim.
