America's word for roundabout, because yielding felt too European.
means A circular junction where traffic flows one-way around a central island, letting cars merge without stoplights (in theory, anyway).
from From Latin 'rota,' meaning wheel — the same root behind 'rotate' and 'rotation.' The traffic sense emerged in the early 20th century as engineers designed circular junctions to keep vehicles moving without crossing paths. The U.S. largely settled on 'rotary,' while Britain kept 'roundabout' — a small linguistic fork that, fittingly, never merged back together.
