Words related to lily
1560s, past-participle adjective from gild (v.). Late Old English had gegylde; Middle English had gilden (adj.). In modern use the more dignified past participle of gild, alternative to gilt. Shakespeare's lilies were never gilded; the quote ("King John," iv.2) is, "To gild refined gold, to paint the lily." Gilded Age as an era in U.S. history (roughly 1870-1900) is from the novel "The Gilded Age" by Mark Twain and Charles Dudley Warner, published in 1873.
also fleur-de-lys, mid-14c., from Anglo-French flour de lis "lily-flower" (see lily), from Old French, literally "flower of the iris," especially borne as a heraldic device on the royal arms of France. There is much dispute over what it is meant to resemble; perhaps an iris flower, or the head of a scepter, or a weapon of some sort. In Middle English often taken as flour delice "flower of joy, lovely flower" (hence Anglo-Latin flos deliciae); also flour de luce "flower of light" (as if from Latin lucem).
"cowardly," 1605, in "Macbeth;" from lily (in its color sense of "pale, bloodless") + liver (n.1), which was a supposed seat of love and passion. A healthy liver is typically dark reddish-brown. Other similar expressions: lily-handed "having white, delicate hands," lily-faced "pale-faced; affectedly modest or sensitive."
