Did you know?

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.” The related but lesser-known terms inculpate (“to incriminate”) and inculpatory (“implying or imputing guilt”) are antonyms of exculpate and exculpatory. A related adjective, culpable, describes someone or something deserving of blame. All of these words are found most often in formal speech and writing, but if you choose to drop them into everyday conversation, your dictionary exculpates you.
