The word 'congestion' means a situation where there is too much of something in one place and it becomes difficult to move or function properly. This word is often used to describe traffic on the roads or when people get sick and their nose gets blocked. For example, "There is a lot of congestion on the highway during rush hour," or "I have congestion in my chest and nose, so I can't breathe properly." It can also be used to describe a crowded space like a stadium or a market.
