Synonym discussion

Sense: adjective/2

All four words describe roads with too many vehicles, but they differ in intensity and register. 'Congested' is the neutral, all-purpose term: it means slow-moving traffic without implying a complete stop ('the main road is congested at 5 p.m.'). 'Clogged' is more informal and suggests a blockage that prevents normal flow, like a drain — traffic is stuck rather than just slow ('traffic is clogged near the tunnel entrance'). 'Gridlocked' is the strongest: it describes traffic that has stopped completely in all directions, often at an intersection, leaving no room to move ('the city was gridlocked after the marathon'). 'Snarled' is informal and suggests tangled, confused traffic that is difficult to untangle ('the accident snarled rush-hour traffic for miles'). Use 'congested' for general descriptions of heavy traffic; reserve 'gridlocked' for extreme situations where nothing moves.

Etymology

LatinEnglish

From Latin 'congestus,' the past participle of 'congerere' — 'com-' (together) and 'gerere' (to carry, bring). The original Latin meaning was 'to heap up' or 'to pile together.' Entered English in the 15th century describing the physical act of collecting or piling. By the 19th century it had developed the medical sense of blood or fluid accumulation, and later the modern traffic and crowding meanings.
