raindrop

noun

1. A single droplet of rainwater that has just fallen or is falling from the sky.

   “It is all so fine and orderly that it would seem that not only had the clouds and streams been kept harmoniously busy in the making of it, but that every raindrop sent like a bullet to a mark had been the subject of a separate thought, so sure is the outcome of beauty through the stormy centuries.”

   “1969, Hal David (lyricist), “Raindrops Keep Fallin' on My Head”.”
