What does master mean?
“Master” is a versatile word whose core meanings are exceptional skill and authority. A master may be an expert in a subject, a person directing an organization or household, or, historically, a teacher. Its senses extend to titles, academic qualifications, and the original or controlling version of a work. In expressions such as “master plan,” the adjective means chief, principal, or authoritative. As a verb, it means to acquire thorough skill in something or gain control over a difficult situation. The word is used in both British and American English and is especially common in discussions of crafts, music, games, and academic study. Although largely neutral or complimentary today, its older association with teachers, rank, and male authority can make it sound formal or hierarchical in some contexts.
A person with exceptional skill or expertise; also a person who holds authority or leadership. The term can also denote a teacher, an honorific title, the holder of a master's degree, or the original from which a copy is made.

Where does master come from?
The word descends from Old English mæster, which was borrowed from Latin magister, meaning “teacher” or “one possessing authority.” Latin magister is also the source of English forms such as magistrate, magisterial, and magistracy; related cognates include German Meister and Dutch meester. Its original educational meaning survives in “master's degree,” while its broader association with authority developed into modern senses involving expertise, command, and control.
