Selected source glosses provide context, not a complete modern definition inventory

From Italian, from Neapolitan and Sicilian lava (“lava; downpour overflowing the streets”), likely from Latin lābēs (“a fall; a collapse; subsidence”); compare lābīna (“landslide”). A supposed relation with lavare (“to wash”) is now widely discredited, nor is there probably any relation with Arabic لابة (lāba, “black volcanic rock”). Alternatively, the Romance words are connected with Provençal lavo, lauvo (“flat stone”), from a Vulgar Latin source borrowed from a Celtic language such as Gaulish *lawā, but ultimately of obscure origin; see Proto-Celtic *līwos for details.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
