insula (plural insulas or insulae)
From Proto-Italic *enselā, of uncertain origin. The relation to similar forms such as Ancient Greek νῆσος (nêsos, “island”) and Proto-Celtic *enistī (“island”) (whence Breton enez, Irish inis and Welsh ynys) is unclear.
Pokorny (1959) tentatively connects it to salum (“the sea”): he posits ellipsis from terra in salō (“land in the sea”) to in (“in”) + salō, invoking the similar Ancient Greek word ἔναλος (énalos, “maritime”). De Vaan considers this derivation phonetically solid, though semantically vague and unlikely. For an alternative he offers a connection of *-sul- to Proto-Indo-European *solh₂- (“place, ground”) as in solum; compare Lithuanian salà (“island”). Perhaps instead of foreign or substrate origin.
