corroborative

Meanings

1. 1
   adj

   serving to support, confirm, or strengthen a statement or conclusion with additional evidence

   Phone records provided corroborative evidence for the witness's account.

From Middle French corroboratif, from corroborer, "to strengthen," and ultimately Latin corroborare. The Latin verb combines com-, an intensifier, with robur, "strength" or "oak." Corroborative evidence therefore strengthens a claim already partly established.
