Related Words

Flood, flash flood, deluge, freshet, inundation refer to the overflowing of normally dry areas, often after heavy rains. Flood is usually applied to the overflow of a great body of water, as, for example, a river, although it may refer to any water that overflows an area: a flood along the river; a flood in a basement. A flash flood is one that comes so suddenly that no preparation can be made against it; it is usually destructive, but begins almost at once to subside: a flash flood caused by a downpour. Deluge suggests a great downpouring of water, sometimes with destruction: The rain came down in a deluge. Freshet suggests a small, quick overflow such as that caused by heavy rains: a freshet in an abandoned watercourse. Inundation, a literary word, suggests the covering of a great area of land by water: the inundation of thousands of acres.

Etymology

Origin of flood

First recorded before 900; Middle English noun flod, Old English flōd; cognate with Gothic flōdus, Old High German fluot ( German Flut )

Explanation

A flood is an enormous amount of water. If the street is full of water, it's flooded. Too much of anything can also be called a flood. Whenever it rains and rains and rains, there's the danger of a flood, a type of disaster where water is out of control. Because a flood is so powerful, people use the word when overwhelmed by other things. A top college graduate could be flooded with job offers — that's a good kind of flood. People can also be flooded with emotion. Words with similar meanings are deluge and overflow. Too much — or just a lot — of anything can seem like a flood.
