From Middle English oven, from Old English ofn (“oven”), from Proto-West Germanic *ofn (“oven”), from Proto-Germanic *uhnaz, *uhwnaz (“oven”). Cognate with West Frisian ûne (“oven”), Dutch oven (“oven”), Low German Aven (“oven”), German Ofen (“oven”), Danish and Norwegian Bokmål ovn (“oven”), Faroese ovnur (“oven”), Icelandic ofn (“oven”), Norwegian Nynorsk omn (“oven”), Swedish ugn (“oven”), Finnish uuni (“oven”), Gothic 𐌰𐌿𐌷𐌽𐍃 (auhns, “oven”)), probably from a Proto-Indo-European *aukʷ- (“cooking pot”), *Hukʷ-, *ukʷnos (compare Sanskrit उखा (ukhā, “boiler, cauldron”), Albanian anë (“vessel, cooker”), Latin aulla, olla (“pot, jar”), Ancient Greek ἰπνός (ipnós, “oven, furnace”)). The modern pronunciation shows a sound change in which Middle English /ɔv/ is changed to /uv/; compare the phonetic development of Coventry and shovel.
