exculpatory

Origin

From exculpate + -ory (suffix forming adjectives with the sense ‘of or pertaining to, serving for’). Exculpate is derived from Medieval Latin exculpātus, perfect passive participle of exculpō (“to free from blame, exculpate”), from ex- (prefix meaning ‘out, away’) + culpa (“defect, fault; crime”) (ultimately from Proto-Indo-European *kʷelp-). Cognate with Spanish exculpatorio.
