The story of the word

The word names an event in the sky, not a climate. At the solstice the sun stops climbing and turns back, and the latitudes where it stands directly overhead at that moment are the tropics of Cancer and Capricorn, so the whole belt between them is named for a reversal. Precession has since moved the sun out of those constellations at the solstices, which leaves both tropic names about two thousand years out of date.
