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

Corroborate is highly evidence-based. You cannot corroborate an opinion with just feelings; you must provide physical proof, data, or witness testimony.

The story behind the word. Corroborate comes from the Latin 'corroborare', which combines 'con-' (together) and 'robur' (oak, or strength). The word 'robur' was used by Romans to describe the hardest wood, specifically oak. Therefore, to corroborate a story is to make it as strong and unyielding as an oak tree by adding supporting evidence.
