- proper n. North Sea Germanic, a postulated grouping of the West Germanic languages that comprises Old Frisian, Old English and Old Saxon.
Sorry, no etymologies found.
What it instead indicates is that there were three "nodes", three centers of change, three wave sources, in the West Germanic dialect continuum: Ingvaeonic, Franconian, and German.
Germans will therefore ridiculously refer to Low German as a dialect of High German, even though they're not even particularly closely related (Low German is Ingvaeonic, and more closely related to English than it is High German).
