North Sea Germanic

**North Sea Germanic**, also known as **Ingvaeonic** , is a group of West Germanic languages that were first spoken in what is now northern Germany, the Netherlands, and Denmark. They were also spread to the British Isles in the Migration Period. The languages were Old Frisian, Old English and Old Saxon. They have become other languages since then and spread worldwide, especially the modern English language.

The grouping was first proposed in *Nordgermanen und Alemannen* (1942) by German linguist and philologist Friedrich Maurer as an alternative to the strict tree diagrams, which had become popular following the work of 19th-century linguist August Schleicher and assumed the existence of a special Anglo-Frisian group. The other groupings are Istvaeonic, from the Istvaeones, which developed into Franconian, and Irminonic, from the Irminones, which developed into Upper German.
## Old Ingvaeonic
Is the proto-language for ingvaeonic and your evolution from Proto-West Germanic.
Nasal before a fricative became a ogonek in the anterior vowel, example:munþ → mųþunþi →  ųþiuns → ųs
Is different from others like Frank; and the dialects of he: Old High Franconian and Old Low Franconian.
The Old Ingvaeonic change ō to œ:Frankō → Francóthe pronunciation became different, look at the pronounce of "Ingƿó":
/iŋˈgwɔːː/ → /iŋˈgwɔː/ → /ˈiŋgwɒ/

## Characteristics
*Palatalisation of velar consonants before front vowels; while the Anglo-Frisian languages further develop these palatal consonants into continuants like in *church*, Old Saxon did undergo palatalisation as evidenced by forms like *kiennan* "know" and *kiesur* "emperor" (contrast German *kennen, Kaiser*) as well as *ieldan* "pay", similar to English *yield*.
*Only four unstressed vowels, those being /i~e/, /æ/, /ɑ/, and /o~u/, all of which are short, though only in Early Old English before the loss of unstressed /æ/
*Lack of i-mutation in s/z-stem plurals; compare Anglian OE  "lambs" with OHG 
*The development of Class III weak verbs into a relic class consisting of four verbs (**sagjan* "to say", **hugjan* "to think", **habjan* "to have", **libjan* "to live")
*The split of the Class II weak verb ending  into : converted  "to make" into 
*Development of a plural ending **-ōs* in a-stem nouns.
*Development of numerous new words, such as the replacement of **newun* "nine" with **nigun* and **minni* "less" (adverb) with **laisi*
Changes originating in Ingvaeonic A, like Old Norse but unlike Gothic and Old High German, include:
