RAIN, n. [Sax. rægn, regn, ren.]

The descent of water in drops from the clouds; or the water thus falling. Rain is distinguished from mist, by the size of the drops, which are distinctly visible. When water falls in very small drops or particles, we call it mist, and fog is composed of particles so fine as to be not only indistinguishable, but to float or be suspended in the air.
