Old Dutch follows Frankish
In linguistics, Old Dutch (Dutch: Oudnederlands) or Old Low Franconian (Dutch: Oudnederfrankisch)  is the set of Franconian dialects (i.e. dialects that evolved from Frankish) spoken in the Low Countries during the Early Middle Ages, from around the 6th or 8th to the 12th century. Old Dutch is mostly recorded on fragmentary relics, and words have been reconstructed from Middle Dutch and Old Dutch loanwords in French.Old Dutch is regarded as the primary stage in the development of a separate Dutch language. It was spoken by the descendants of the Salian Franks who occupied what is now the southern Netherlands, northern Belgium, part of northern France, and parts of the Lower Rhine regions of Germany. It evolved into Middle Dutch around the 12th century. The inhabitants of northern Dutch provinces, including Groningen, Friesland, and the coast of North Holland, spoke Old Frisian, and some in the east (Achterhoek, Overijssel, and Drenthe) spoke Old Saxon.Bergakker inscription (425–450)
Haþuþȳwas. Ann kusjam logūns.
This sentence has been interpreted as "Haþuþyw's. I/He grant(s) a flame (i.e. brand, sword) to the select". It was discovered on a sword sheath mounting, excavated in 1996 in the Dutch village of Bergakker and is perhaps better described as Frankish than Old Dutch (Frankish was the direct parent language of Old Dutch). The text however, shows the beginning of Old Dutch morphology. The word ann, found in the partially-translated inscription is coined as the oldest Dutch by linguists Nicoline van der Sijs and Tanneke Schoonheim from Genootschap Onze Taal. They attribute that word to the ancestor of the modern Dutch verb root gun, through the addition of the prefix ge-. (An English cognate probably survives in to own (up) in the sense of 'to acknowledge, concede'.) Its modern meaning is roughly "to think someone deserves something, to derive satisfaction from someone else's success", and it is commonly translated as "grant" or "bestow".
