[ˈɫa.kʊs], [ˈlaː.kus]
OriginFrom Proto-Italic *lakus, from Proto-Indo-European *lókus (“lake, pool”); the reason for the change to *a is debated, but likely from velarized *[ɫ]. Cognate with Ancient Greek λάκκος (lákkos, “cistern, tank, pit”) and Old English lagu (“sea, ocean, flood”). More at lay.
