A circle's circumference is the boundary or line that encloses it. The term comes via Old French from Latin circumferentia. Formed from circum, ‘around’, and ferre, ‘to carry’. English words beginning circum- all share some idea of ‘going around’ in their meaning. To circumscribe (Late Middle English) comes from Latin circum and scribere ‘to write’, circumspect (Late Middle English) literally means ‘looking around’, and circumcise (Middle English) ‘to cut round’. If you circumvent a problem (from Latin venire ‘to come’), you find a way round it, and if you circumnavigate (early 17th century) the world you sail round it. Circumstances (Middle English) come from Latin cimcumstare, ‘stand around’.
