wick
fibre
wick, thread, strip, or bundle of fibres that, by capillary action, draws up the oil of a lamp or the melted wax in a candle to be burned. By 1000 bc, wicks of vegetable fibres were used in saucer-type vessels containing olive oil or nut oil in order to provide light, and by 500–400 bc these wicks were in general domestic use. See lamp.
