a tiny rain god summoned by Tuesdays and the threat of a dead lawn
means A device that scatters water in droplets over a lawn, garden, or — in ceilings — to douse fires.
from From the verb "sprinkle," which traces back to Middle English "sprenkelen," likely a frequentative form meaning "to scatter in small drops." It's related to Middle Dutch "sprenkelen" and a family of Germanic words for speckling and spattering — the same root cluster that gives us "speckle" and the sense of small scattered spots. The "-er" ending is the plain old agent suffix, turning the act of sprinkling into the thing that does the sprinkling.
