sinister (English)
Where does "sinister" come from?
The English word 'sinister' evolved from the Middle English 'sinistre', meaning 'unlucky'[1]. This term traces back to the Old French 'senestre'[1], which derived from the Latin 'sinister', a word literally denoting the 'left hand'[1][2]. The transition from a simple spatial direction to a term for 'evil' or 'inauspicious' reflects deep historical associations between the left side and perceived moral or superstitious inferiority[1][2].
