Etymology
'circuit' originates from Latin, specifically the word 'circuitus', where 'circum' meant 'around' and 'ire' meant 'to go'.
'circuitus' passed into Old French as 'circuit' and then into Middle English as 'circuit', eventually becoming the modern English word 'circuit'.
Initially it meant 'a going around' or 'a round-trip', but over time it evolved to mean 'a route or course' and later extended to technical senses such as an electrical path and figurative senses like a series of events.
