köken: Borrowed from Latin tropus (“figure of speech, trope”), from Ancient Greek τρόπος (trópos, “turn; figure of speech; musical mode”). The “tropics” sense (etymology 1 sense 1) is possibly a semantic loan from German Tropen (“tropics”). The phonetic form was probably influenced by trópus (“trope”), which was borrowed independently from the same Latin term. First attested in 1833.
the tropics (the region of the Earth centred on the equator and lying between the Tropic of Cancer and the Tropic of Capricorn and characterized by a hot climate)
