Westphalian is one of the major dialect groups of 
Low Saxon. Its most salient feature is the diphthongization (rising diphthongs). For example, we get 
iEten instead of 
E:ten for 
eat. The Westphalian dialect region includes the northern part of 
North Rhine-Westphalia, i.e. the former 
Prussian province of Westphalia excluding the 
Siegerland[?] and the region around 
Osnabrück.
