This word is derived from medieval Latin exculpatus, traces back to the Latin noun culpa, meaning “blame.” Some other descendants of “culpa” in English include “culpable” (“meriting condemnation or blame”) and “inculpate” (“incriminate”), as well as the considerably rarer “culpatory” (“accusing”) and “disculpate” (a synonym of “exculpate”). Also, “mea culpa” which translates directly as “through my fault” and is used in English to mean “a formal acknowledgment of personal fault or error.”
The court will exculpate him of the crime after the real criminal confesses.
I will present evidence that will exculpate my client.
