Etymology

master = mast<great, chief> + er<agent suffix>

  • mast (from Old English mægester, Latin magister <great, chief>)
  • er (agent suffix indicating a person, from Old English -ere)

Etymology Origin:
The word "master" traces back to Latin magister (meaning "chief, teacher"), which itself derives from magis ("more, great"). It entered Old English as mægester and evolved to signify authority or expertise. The suffix -er reinforces its role as a title for someone who commands or excels. Over time, "master" expanded from denoting feudal lords to experts in crafts, academics, and skills.
