Borrowed from Italian lazzareto (古風な用法), lazzaretto, lazzeretto, from lazzaro (“leper”) + -etto (diminutive または meliorative suffix).[1] Lazzaro is derived from Medieval Latin lazarus (“leper”), from Lazarus, from Ancient Greek Λᾱ́ζᾱρος (Lā́zāros), from Hebrew אֶלְעָזָר ('el'azár, literally “God has helped”), from אֵל ('él, “God; a deity, god”) + עָזַר ('azár, “to assist, help”). Lazarus is a Biblical character mentioned in the parable of Jesus known as “The rich man and Lazarus” who is described as being a beggar covered in sores: see Luke 16:20–21. Doublet of lazar and lazaret.
The plural form lazaretti is borrowed from Italian lazzaretti, lazzeretti.
