Word Origin & Etymology

Borrowed from Latin 'genius', originally meaning an attendant guardian spirit present from birth, derived from the root 'gignere' ('to beget' or 'to produce'). By the 17th and 18th centuries, the meaning shifted from an external guiding spirit to an individual's innate intellectual and creative power.
