During the Merovingian period, the Central Franconian dialects were influenced by Old Low Franconian (Old Dutch), resulting in certain linguistic loans which yielded a slight overlap of vocabulary, most of which relates to warfare. In addition is the subsumption of the High German consonant shift, a set of phonological changes beginning around the 5th or 6th century that partially influenced Old Dutch, and extensively influenced Central Franconian and other Old High German dialects.
