exculpatory
adj [ɪkˈskʌlpəˌtɔri]
Something described as exculpatory serves to prove that someone is not guilty of doing something wrong.
Exculpatory is the adjectival form of the verb exculpate, meaning “to clear from guilt.” The pair of words cannot be accused of being secretive—their joint etymology reveals all: they are tied to the Medieval Latin verb exculpare, a word that combines the prefix ex-, meaning “out of” or “away from,” with the Latin noun culpa, meaning “blame.”
