(function)
purpose or role
Etymology
'function' originates from Latin, specifically the noun 'functio' (from the verb 'fungi'), where the root meant 'to perform, execute'.
'function' came into English via Latin through Old French (Middle French 'fonction') and Middle English, evolving from Latin 'functio' to the modern English 'function'.
Initially, it meant 'the action of performing or executing' (a performance or execution); over time it broadened to include 'purpose, role, operation' as primary senses.
