From exculpate + -ory (suffix forming adjectives with the sense ‘of または pertaining to, serving for’).[1] Exculpate is derived from Medieval Latin exculpātus and Latin exculptus, the perfect passive participle of exculpō, from ex- (prefix meaning ‘out, away’) + culpa (“defect, fault; crime”) (ultimately from Proto-Indo-European *kʷelp-).[2]
exculpatory (comparative more exculpatory, superlative most exculpatory)
