The language from which Old Dutch (also sometimes called Old West Low Franconian, Old Low Franconian or Old Frankish) arose is unknown with certainty, but it is thought to be the language spoken by the Salian Franks. Even though the Franks are traditionally categorized as Weser-Rhine Germanic, Dutch has a number of Ingvaeonic characteristics and is classified by modern linguists as an Ingvaeonic language . Dutch also has a number of Old Saxon characteristics. There was a close relationship between Old Dutch, Old Saxon, Old English and Old Frisian. Because texts written in the language spoken by the Franks are almost non-existent, and Old Dutch texts scarce and fragmentary, not much is known about the development of Old Dutch. Old Dutch made the transition to Middle Dutch around 1150.
