What does congested mean?
"Congested" describes something so blocked or overcrowded that normal movement or flow becomes difficult. It is most commonly applied to traffic — a congested road, junction, or city centre is one where vehicles move slowly or not at all — but it has an important medical sense as well: congested nasal passages are blocked with mucus, and in clinical language, organs such as the liver or lungs can be described as congested when they contain an excess of blood or fluid. The word carries a mildly negative connotation of frustration and dysfunction, which is why it features so prominently in discussions of urban planning and public health. Derived from the Latin verb congerere, meaning "to pile up" or "bring together," it entered English in the sixteenth century alongside its noun form, congestion. Its relatives include digest, gesture, and gesticulate, all built on the same Latin root gerere, "to carry or bear." Whether describing a gridlocked motorway or a blocked nose, congested vividly conveys the idea of too much accumulating in too little space.
adjectiveBlocked or overcrowded so that movement or flow is impeded, as with traffic or nasal passages; also used medically to describe tissue or organs abnormally full of fluid or blood.
- (of traffic or a place) blocked or overcrowded to the point that movement is slow or impossible.
- (medicine) (of a body part, especially mucous membranes) abnormally full of fluid or blood; blocked.
- (medicine, of internal organs such as the liver or lungs) containing an excess of blood or other fluid.
"The congested motorway stretched for miles in both directions."
"Commuters spent over an hour crawling through the congested city centre."
"She took a decongestant to relieve her congested sinuses before the flight."
The same Latin root that gives us "gesture" and "digest" gave us "congested" — literally "piled up together," which is exactly what your sinuses and the M25 have in common.
