ellipseyoudaoicibaDictYouDict[ellipse 词源字典]
ellipse: [18] Greek élleipsis meant literally ‘defect, failure’. It was a derivative of elleípein, literally ‘leave in’, hence ‘leave behind, leave out, fall short, fail’, a compound verb formed from the prefix en- ‘in’ and leípein ‘leave’ (which is related to English loan and relinquish). It was borrowed into English in the 17th century as ellipsis in the grammatical sense ‘omission of a word or words’, but its mathematical use for an ‘oval’ (enshrined in the form ellipse, borrowed via French ellipse and Latin ellīpsis) comes from the notion that a square drawn on lines passing vertically and laterally through the centre of an ellipse ‘falls short’ of the entire length of the lateral line.
