Because there is evidence that Lombardic participated in, and indeed shows some of the earliest evidence for, the High German consonant shift, it is classified as an Elbe Germanic or Upper German dialect. The Historia Langobardorum of Paulus Diaconus mentions a duke Zaban of 574, showing /t/ shifted to /ts/. The term stolesazo (ablative)[3] (the second element is cognate with English seat) in the Edictum Rothari shows the same shift.
