A bundle of fibers, or a loosely twisted or braided cord, tape, or tube, usually made of soft spun cotton threads, which by capillary attraction draws up a steady supply of the oil in lamps, the melted tallow or wax in candles, or other material used for illumination, in small successive portions, to be burned.
A revolutionary poem will not tell you who or when to kill, what and when to burn, or even how to theorize. It reminds you... where and when and how you are living and might live, it is a wick of desire. Adrienne Rich
The lamp burns bright when wick and oil are clean. Ovid
It is a great pity but tis certain from every day's observation of man, that he may be set on fire like a candle, at either end provided there is a sufficient wick standing out. Laurence Sterne
