Etymology
Etymology Information

'mastermind' originates from English, specifically a compound of 'master' and 'mind', where 'master' ultimately comes from Latin 'magister' through Old French 'maistre' meaning 'teacher/chief', and 'mind' comes from Old English 'gemynd' meaning 'memory' or 'thought'.

Historical Evolution

'mastermind' developed as a compound in modern English in the late 19th century (recorded uses from the 1800s) combining 'master' + 'mind' and became used to describe an especially able planner; it later gained senses referring specifically to the organizer of secret or criminal schemes.

Meaning Changes

Initially, the word emphasized exceptional intelligence or skill (an especially clever or brilliant person); over time it came to emphasize the role of planning and directing complex (often secret or illicit) operations and schemes.
