Etymology

The word combines "right," from Old English riht (meaning "straight, correct, or the opposite of left"), and "hand," from Old English hand (referring to the body part). Historically, the right side was culturally associated with strength and virtue (Latin dexter), while the left (sinister) carried negative connotations. "Right-hand" emerged in Middle English to denote literal position (e.g., "right-hand side") and figuratively for dependability (e.g., "right-hand man").
