A sudden, unexpected, and often strange change, action, or idea.
Etymology
The word 'vagary' entered English in the late 16th century from the Latin 'vagari', which means 'to wander'. This Latin root is itself derived from the Proto-Indo-European (PIE) root wāgh-, meaning 'to go, transport'. The original English sense was closely tied to the physical act of wandering, describing the unpredictable course of a journey or a wandering of the mind. Over time, the meaning evolved from a literal wandering to a metaphorical one, capturing the essence of an unpredictable, whimsical, or erratic turn of events, action, or thought, which is its modern abstract meaning.
Analysis
The word is a simplex loanword. It originates from the Latin verb 'vagari' meaning 'to wander, roam, or be unsettled'.
