Definition & Meaning of "bloody"in English

What is the origin of the term "bloody" and how is it used?

Bloody is an adjective that appeared in English by the 17th century as an expletive used to express anger, annoyance, or emphasis. Its origin is debated: it may relate to "by our Lady" (a mild oath invoking the Virgin Mary) or to literal references to blood for shock value. Historically, it was considered vulgar and offensive, particularly in British English, though over time it became milder and more common in everyday speech. Today it remains informal, often used to intensify statements, show irritation, or add emphasis in casual conversation.
