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).
"porch at the west end of early churches," the end furthest from the sanctuary (used by penitents not admitted to the body of the church), 1670s, from Late Greek narthex, in classical Greek "giant fennel," a word of unknown origin, perhaps Pre-Greek. The architectural feature allegedly was so called from the fancied resemblance of the porch to a hollow stem. The word also was used in Greek to mean "a small case for unguents, etc." According to Hesiod ("Theogeny"), Prometheus conveyed fire from Heaven to Earth in hollow fennel stalks. Related: Narthecal.
"full bloom, period or act of blooming, time that the flower is expanded," 1811, from Greek anthesis, noun of action from antheein "to blossom," from anthos "flower" (see anther).
