"Mea culpa" is a Latin phrase that means "through my fault." It is an acknowledgment of one's own responsibility for a mistake or wrongdoing. When someone uses "mea culpa," they are admitting that they have made an error and are taking the blame for it. This phrase is often used in a formal context, such as in public apologies or confessions.
"Mea culpa" originates from Latin, combining "mea," meaning "my," and "culpa," meaning "fault" or "blame." The phrase has been used since medieval times, especially in religious contexts, to express repentance and accountability.
