It's Been Too Long...

...too long, in fact, I had to look it up:

rain |rān| noun moisture condensed from the atmosphere that falls visibly in separate drops : the rain had not stopped for days | it's pouring rain. • ( rains) falls of rain : the plants were washed away by some unusually heavy rains. • [in sing. ] a large or overwhelming quantity of things that fall or descend : he fell under the rain of blows.
