Origin of 'circumference'

Main points about word origin

  • The word comes from the Latin 'circumferre,' which means 'to carry around.'
  • In Ancient Greek, 'kuklos' means 'circle,' which is the foundation of many words related to round shapes.

The word 'circumference' originated from the Latin word 'circumferentia', which is a combination of 'circum' (around) and 'ferre' (to carry). It has been used in geometry to describe the boundary of a circle since ancient times. The concept of circumference is fundamental in geometry and has been studied by mathematicians for centuries.
