Etymology

1. According to De Vaan, from Proto-Italic *lakus, from Proto-Indo-European *lókus (“lake, pool”); the reason for the change to *a is debated, but perhaps from velarized *[ɫ]. Regarding this proposed phonological development, Schrijver notes that the form lacus may be the only positive evidence for such a sound law, rendering the existence of the rule uncertain.
2. Cognate with Ancient Greek λάκκος (lákkos, “cistern, tank, pit”) and Old English lagu (“sea, ocean, flood”). More at lay. See: Ancient Greek Nouns 'λάκκος', Old English Nouns 'lagu'.
