Inherited from Middle English Neweton, from Old English nēowa tūn (“new town”). Compare same construction in Italian Napoli (“Naples”) and in Arabic نَابُلُس (nābulus, “Nablus”). The unexpected Early Modern pronunciation with /ɛʊ̯/, as securely attested in Richard Hodges' 1644 English Primrose and confirmed by obsolete Welsh Newtwnn, is due to trisyllabic shortening in Old English nēowa tūn or Middle English Neweton.
