While the Northern Rhineland, Westphalia and Lippe are different historic territories of today's North Rhine-Westphalia, the old border between the former Rhine Province and the Province of Westphalia is also a language border. While in Westphalia and Lippe, people tend to speak West Low German dialects and especially the Westphalian variant of the Low German language, Central German and Low Franconian dialects are spoken in the Northern Rhineland.
