Referring to the phases of the Moon (about 14th century). (Compare wax with the German cognate wachsen (“grow”).) By folk etymology, this verb phrase has occasionally been mistakenly presumed to be a reference to candles, under the notion that waxing of a wick (applying wax) produces a candle that, once lit, immediately begins to wane away until complete darkness.
