語源
英語の原文（Wiktionary）
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.
