The word 巫师 is formed by combining two meaningful characters: 巫, which historically refers to a shaman, spirit medium, or practitioner of ancient rituals and divination; and 师, meaning master, teacher, or specialist. Their fusion creates a composite concept where the second character elevates and professionalizes the first, transforming the base idea of a "shaman" into the more formalized and respected role of a "master of mystical arts" or "sorcerer". This formation reflects a cultural synthesis where specialized knowledge and skill are recognized as a teachable craft or authoritative profession derived from ancient spiritual practices.
