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

The story behind the word. Derived from Latin 'com-' (together) and 'roborare' (to strengthen), which comes from 'robur' meaning 'oak tree' or 'hardwood strength'. To corroborate a story is literally to make it as solid and sturdy as an oak tree.
