The development of syntactic system of Roman German Languages

Germanic languages by number of native speakers (in millions)

History

• All Germanic languages are thought to be descended from a hypothetical Proto-Germanic, united by subjection to the sound shifts of Grimm's law and Verner's law. These probably took place during the Pre-Roman Iron Age of Northern Europe from c. 500 BC. Proto-Germanic itself was likely spoken after c. 500 BC, and Proto-Norse from the 2nd century AD and later is still quite close to reconstructed Proto-Germanic, but other common innovations separating Germanic from Proto-Indo-European suggest a common history of pre-Proto-Germanic speakers throughout the Nordic Bronze Age.
• From the time of their earliest attestation, the Germanic varieties are divided into three groups: West, East, and North Germanic. Their exact relation is difficult to determine from the sparse evidence of runic inscriptions.
• The western group would have formed in the late Jastorf culture, and the eastern group may be derived from the 1st-century variety of Gotland, leaving southern Sweden as the original location of the northern group. The earliest period of Elder Futhark (2nd to 4th centuries) predates the division in regional script variants, and linguistically essentially still reflects the Common Germanic stage. The Vimose inscriptions include some of the oldest datable Germanic inscriptions, starting in c. 160 AD.

• Longer runic inscriptions survive from the 8th and 9th centuries (Eggjum stone, Rök stone), longer texts in the Latin alphabet survive from the 12th century (Íslendingabók), and some skaldic poetry dates back to as early as the 9th century.
• By about the 10th century, the varieties had diverged enough to make mutual intelligibility difficult. The linguistic contact of the Viking settlers of the Danelaw with the Anglo-Saxons left traces in the English language and is suspected to have facilitated the collapse of Old English grammar that, combined with the influx of Romance Old French vocabulary after the Norman Conquest, resulted in Middle English from the
• The North Germanic languages, on the other hand, remained unified until well past 1000 AD, and in fact the mainland Scandinavian languages still largely retain mutual intelligibility into modern times. The main split in these languages is between the mainland languages and the island languages to the west, especially Icelandic, which has maintained the grammar of Old Norse virtually unchanged, while the mainland languages have diverged greatly. 12th century.
