The word 'drain' usually refers to something that helps to remove water or liquid from a place or a container. For example, a sink has a drain where water flows out. Similarly, a shower or bathtub also has a drain so that the water can go out. When it rains heavily, the water may collect on the road and may need to be drained using gutters or a drainage system. The word 'drain' can also be used to describe a feeling of exhaustion or depletion of energy, like "I feel drained after a long day of work."
