RAIN, v.i. [It seems that rain is contracted from regen. It is the Gr. to rain, to water, which we retain in brook, and the Latins, by dropping the prefix, in rigo, irrigo, to irrigate. The primary sense is to pour out, to drive forth. Heb.]
RAIN, v.t. To pour or shower down from the upper regions, like rain from the clouds.
RAIN, n. 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.
