Picture an ancient map: its east-west span seemed enormous, while its inhabited world was comparatively narrow from north to south. Latin geographers called that shorter “breadth” latitūdō, built from lātus, “broad,” a word whose ancestry may reach back to the reconstructed Proto-Indo-European form *stleto-, “to spread.” English borrowed latitude from Old French in the late 14th century, and the mapmaker’s idea of breadth soon became an angular measurement running from the Equator to the poles. That is why lines of latitude are called parallels: they spread east-west without converging, while latitude itself measures how far north or south you have wandered. In another figurative turn, latitude became room to maneuver—so having “latitude” means that an old idea of physical breadth has become intellectual elbow room.
