What Does Mea Culpa Mean? | Definition & Examples

Mea culpa comes from the Latin for “my fault,” or “through my fault.” It is an interjection (i.e., a word or phrase that expresses a feeling) but can also be used as a noun meaning an admission of guilt (e.g., “The senator issued a mea culpa via the press office”).

Mea culpa has a long history in English dating back at least to Chaucer (14th century) and originates in a prayer of confession in the Roman Catholic Church. It is now used in a much more general sense to indicate that you accept being at fault for something.

Examples: Mea culpa in a sentence
Did I leave the door unlocked? Mea culpa! I’m so sorry!

The letter was nothing but a three-page mea culpa from the assistant.

The doctor’s short mea culpa on the website did little to calm the patients’ anger.

Because mea culpa has been used in English for so long (like “ad hoc,” “in vitro,” and “de facto”), it does not need to be italicized in the way more recent loanwords from other languages do.
