Which word means to relieve of blame?

The term "exculpate" specifically means to clear someone from blame or fault; it comes from the Latin word “exculpare,” which means "to free from blame." This word is often used in legal contexts or discussions where someone is proving their innocence or being absolved of any wrongdoing.

Understanding this term can help in contexts where accusations are addressed, and the need to establish someone’s innocence is vital. The other terms presented have distinct meanings. "Expiate" involves making amends or atoning for wrongdoing, rather than relieving someone from blame. "Expropriate" refers to the act of taking away property for public use, generally involving compensation, which is not related to clearing blame. Lastly, "extant" describes something that still exists; it does not pertain to blame or fault at all. Therefore, "exculpate" is the only term that accurately denotes the act of relieving someone from blame.
