A type of candle made from a rush plant wick soaked in fat or grease.
In the old days, people often used a rushlight to light their homes at night.
Rushlight → It is formed from "rush" (from Old English *rysce*, meaning a type of wetland plant) and "light" (from Old English *leoht*, meaning illumination). A rushlight is a light source made from the rush plant, typically used in earlier times for illumination.
Think of the rush plant, which provides a natural source for making light — that's how a rushlight serves as a light source.
