When some of them moved to the south, they mangled the language
No. Lusatians believe that they came from South and separated directly from Southern Serbs and, then ancestors of today`s Poles separated and spread more eastern and, as genetic science confirms, ancestors of today`s Russians separated from Polish ancestors and moved even more eastward.
