where roads briefly date everyone before committing to exactly one direction.
means A point where two roads or systems connect so traffic, goods, or information can move between them — or, as a verb, to swap or exchange things back and forth.
from A straightforward English assembly from the prefix 'inter-' (Latin for 'between, among') and 'change,' which came through Old French 'changier' from Latin 'cambiare,' meaning 'to barter or exchange' — itself thought to have Celtic roots. So the word literally means 'changing between,' first used of swapping things and only much later borrowed by highway engineers for the tangled crossings where roads trade lanes.
