Etymologia

From Middle English foyle, from Middle French fueille, from Old French fueille (“plant leaf”), from Late Latin folia, the plural of folium, mistaken as a singular feminine.
The literary sense is from the practice of backing a gem with metal foil to make it shine more brilliantly.
Doublet of folio and folium, distantly also with phyllo and phyllon.
