The term FLOOD (IN) can be solved by the four-letter word POUR. Flooding is a natural phenomenon that occurs when an area of land is submerged in water, usually due to heavy rainfall or a river overflowing its banks. Floods can cause significant damage to property and infrastructure, as well as loss of life. Pouring is the act of releasing a large amount of liquid in a short period of time, which can be seen as a metaphor for flooding.
