The word "congestion" refers to the state of being overcrowded or filled with too much of something, often leading to a blockage or difficulty moving. It is commonly used to describe situations where there is an excessive accumulation of people, vehicles, or fluids in a particular space. For example, traffic congestion occurs when too many vehicles are on the road, causing delays and slow movement. In medical contexts, congestion can refer to the excessive fluid in the lungs or nasal passages.
The word "congestion" comes from the Latin "congestio," which means "a bringing together." This is derived from "congerere," meaning "to bring together," composed of "com-" (together) and "gerere" (to carry).
