What does mea culpa mean?

Mea culpa is the Latin way of saying my bad. It literally means “through my (own) fault.”

Mea culpa can be used as an interjection (much like my fault or my bad) or as a noun referring to an apology, as in The senator offered a mea culpa during the press conference.

Example: Dave usually has a hard time admitting he’s wrong, so his mea culpa means a lot.

Where does mea culpa come from?

Mea culpa is a direct loan of a Latin phrase meaning ‘through my (own) fault.” It’s made of the parts mea, meaning “by me” or “through me,” and culpa, meaning “fault.” Culpa is also the root of the words culpable, meaning “deserving blame,” and culprit, meaning “a person guilty of something.”

The phrase mea culpa comes from a Roman Catholic prayer for confessing sin and seeking forgiveness. One line of the prayer is mea culpa, mea culpa, mea maxima culpa, which is usually translated as “through my own fault, through my own fault, through my most grievous fault.”

The phrase was borrowed directly from this prayer and has been in use as an admission of guilt since at least the 1200s. The noun form referring to an apology seems to be much newer, with the first records of it coming from the 1800s. The phrase is now commonly used both ways. When you eat your roommate’s leftover burrito without asking, you could say mea culpa, or you could offer a mea culpa by admitting that you did it and saying that you’re sorry. Or you could just stop eating your roommate’s food!
