n. The descent of water in drops through the atmosphere, or the water thus falling.n. Figuratively— A fall of any substance through the atmosphere in the manner of rain, as of blossoms or of the pyrotechnic stars from rockets and other fireworks.n. A shower, downpour, or abundant outpouring of anything.n. Synonyms Rain, Haze, Fog, Mist, Cloud. A cloud resting upon the earth is called mist or fog. In mist the globules are very fine, but are separately distinguishable, and have a visible motion. In fog the particles are separately indistinguishable, and there is no perceptible motion. A dry fog is composed largely of dust-particles on which the condensed vapor is too slight to occasion any sense of moisture. Haze differs from fog and cloud in the greater microscopic minuteness of its particles. It is visible only as a want of transparency of the atmosphere, and in general exhibits neither form, boundary, nor locus. Thus, among haze, fog, mist, and rain, the size of the constituent particles or globules is a discriminating characteristic, though frequently cloud merges into fog or mist, and mist into rain, by insensible gradations.To fall in drops through the air, as water: generally used impersonally.To fall or drop like rain; as, tears rained from their eyes.To pour or shower down, like rain from the clouds; pour or send down abundantly.n. A ridge.n. A furrow.n. An obsolete spelling of rein.n.
