catacomb

From Middle English catacombe, from Old English catacumbe, catacumbas pl, from Late Latin catacumbae pl, name of the underground cemetery of St. Sebastian in Rome, of unclear origin. Perhaps a dissimilation (influenced by *cumbō (“to lie, recline”)) of Late Latin cata tumbās (literally “among the tombs”) (from Ancient Greek κατά (katá, “under”) and τύμβος (túmbos, “tomb”)).[1][2] Some sources suggest Ancient Greek κύμβη (kúmbē, “drinking vessel”) as an alternative etymon, but the semantic link is unclear.[3]
