Delay refers to a situation where something happens later than expected or planned. For example, if a train is scheduled to arrive at 3 PM but doesn't show up until 3:30 PM, we say there is a delay. Delays can occur in various aspects of life, such as travel, work, or even waiting for a friend. Delays can be caused by many factors, like bad weather, traffic jams, or technical issues. For instance, a flight might be delayed due to a storm, affecting passengers' plans. Understanding delays helps us manage our time better and stay patient when things don't go as planned.
