词源

  • tropic回归线
    tropic 源于希腊词 tropikos。实际上它和trohpy (奖品,战利品)一样,同是出自希腊根词trop'turn'(转向,转动)。用tropic 来指“回归线”是因为回归线是太阳所能到达的极限位置,太阳到达此处,不是转向南去,就是转向北去。北回归线英语说Tropic of Cancer,南回归线英语说Tropic of Capricorn。tropic 的复数形式,即tropics,则被用以指现回归线和北回归线之间的地带,即“热带”。英语中有一个修辞学术语trope(转义,比喻)其终极词源也是希腊词根trope。
  • tropic回归线,热带,热带地区
    来自拉丁语 tropicus,夏至的,回归线的,来自希腊语 tropikos kyklos,旋转圈,回归线圈,来 自 trope,转向,旋转,词源同 turn,trope,kyklos,圈,词源同 cycle.引申词义热带,热带地区, 即太阳的直射点最远可以到达的区域。
  • tropic
    From Late Latin tropicus ‎(“of or pertaining to the solstice, as a noun, one of the tropics”), from Ancient Greek τροπικός ‎(tropikós, “of or pertaining to a turn or change; or the solstice; or a trope or figure; tropic; tropical; etc.”), from τροπή ‎(tropḗ, “turn; solstice; trope”).
