As adjective < (iii) Middle French tropic, tropicque, tropike, tropique (French tropique ) (in grammar) of or relating to a trope (c1375), relating to the sun's change of direction at the solstices, relating to one or other tropic (in sense A. 1b or A. 1c) (1550 or earlier), and its etymon (iv) classical Latin tropicus of or belonging to a solstice or equinox, (in later use, in grammar) of or belonging to a figure of speech (2nd cent. a.d.) < ancient Greek τροπικός of or relating to the solstice, tropical, in Hellenistic Greek also of the nature of a trope, figurative < τροπή trope n. + -ικός -ic suffix.
