chalice (n.)

"drinking-cup or bowl," early 14c., from Anglo-French chalice, from Old French chalice, collateral form of calice (Modern French calice), from Latin calicem (nominative calix) "cup," similar to, and perhaps cognate with, Greek kylix "cup, drinking cup, cup of a flower," but they might both be loan-words from the same non-IE language. Ousted Old English cognate cælic, an ecclesiastical borrowing of the Latin word, and earlier Middle English caliz, from Old North French.
