Drizzle

As a noun, it is very light rain made of fine drops. As a verb, it means to rain in this light way, or to pour a thin stream of liquid over food.

From Middle English 'drisling', related to Old English 'drēosan' meaning 'to fall', and possibly linked to 'dross'. The word imitates the soft, gentle nature of the rain. Over time, it was also applied to thin streams of other liquids in cooking.
