OriginLate Middle English (denoting the point on the ecliptic reached by the sun at the solstice): via Latin from Greek tropikos, from tropē 'turning', from trepein 'to turn'. trophy from Late Middle English: Both tropic (Late Middle English) and trophy are ultimately from Greek trepein ‘to turn’. In ancient Greece and Rome a trophy was a pile of the weapons of a defeated army set up as a memorial of a victory. The attractive young trophy wife of a successful older man, is a term first used in the late 1980s. A tropic is a ‘turning point’, a point on the path through the sky that the sun can be seen to take through the year where, at the solstice, it appears to turn back again towards the equator.
