The word "大侠" is formed by combining the character "大", meaning "big" or "great", with the character "侠", meaning "knight-errant" or "chivalrous person". Together, they create a compound word where "大" intensifies "侠", resulting in a term that denotes a "great hero" or "master warrior", specifically referring to an exemplary figure in wuxia literature known for extraordinary martial arts skills and a steadfast moral code.
