A single drop of rain falling from a cloud to the ground.
Compound word from Old English 'regn' (rain) and 'dropa' (drop). Both elements have Germanic roots; 'regn' is related to Old High German 'regan' and 'dropa' to Old Saxon 'dropo'.
A raindrop is actually shaped like a hamburger bun, not a teardrop—the flat bottom and rounded top form as it falls through the air, and surface tension keeps it from flattening into a perfect sphere.
