a traffic circle that solved gridlock by politely refusing to ever fully stop.
means A circular road junction where traffic flows around a central island, yielding rather than halting; the word also means indirect or roundabout in manner, and once named a children's merry-go-round.
from A transparent English compound of "round" plus "about," both old Germanic-rooted words — "round" came into Middle English via Old French "reond" (ultimately from Latin "rotundus," wheel-shaped), while "about" descends from Old English "onbutan," meaning on the outside of. "Roundabout" appears from the 16th–17th centuries first as an adjective and adverb for anything circular or circuitous, then gathered concrete meanings over time: a fairground carousel, and later the traffic circle. The road sense is the youngest of the family.
