This unglossed headword, lacking (Adler reports) in mss AFV, is also the final word of the previous entry, lambda 367 (q.v.).
The word is defined as "gift" in Hesychius. It is defined as "greed" in ps.-Zonaras, and occurs in Early Modern Greek in that meaning (Chronicle of the Tocci 10.9,; A. Guillou, Les archives de Saint-Jean-Prodrome sur le mont Ménécée [Bibliothèque Byzantine Documents 3. Paris: Presses Universitaires de France, 1955] p. 175). The related adjective lei/couros "gluttonous", from which the noun is actually derived, is defined in ps.-Zonaras, and occurs in Philogelos 243 with that meaning.
Kriaras (Dictionary of Mediaeval Greek Vernacular Writing) does derive li/couros from li/chs = lixa. He also records the Early Modern verb liceu/w "long for" and noun licia/ "greed", which corroborates an original l[e]ic- stem. Trapp and LSJ prefer to derive leicouri/a from lei/xw, following Hesychius.
