lavabrum

== Latin == === Etymology === Perhaps inherited from Proto-Indo-European *lówh₃trom with analogical remodeling after lavō (“to wash, bathe”) and a secondary recharacterization with -brum. However, it is also possibly an innovative Latin formation from lavō +‎ -brum. Compare Gaulish lautron, Old Irish loathar (< Proto-Celtic *lowatrom), Proto-Germanic *lauþrą, Ancient Greek λουτρόν (loutrón) and Mycenaean Greek *𐀩𐀺𐀵𐀫 (*re-wo-to-ro /⁠*lewotron⁠/) (< Proto-Hellenic *lewotrón). Compare the Celtic-origin place-names Lavatrae and Laudradum. === Noun === lavābrum n (genitive lavābrī); second declension archaic spelling of lābrum (“bathtub”) ==== Declension ==== Second-declension noun (neuter). === References === “lavabrum”, in Gaffiot, Félix (1934), Dictionnaire illustré latin-français, Hachette.
