Northwest Germanic is a proposed grouping of the Germanic dialects. It does not challenge the accepted tri-partite division of the Germanic dialects into North Germanic, West Germanic and East Germanic, but proposes additionally that North and West Germanic remained as a subgroup after the southward migration of the East Germanic tribes, only splitting into North and West Germanic later. Whether this subgroup constitued a unified proto-languagage, or simply represents a group of dialects that remained in contact and close geographical proximity is a matter of debate. The date by which such a grouping must have dissolved - in that innovations ceased to be shared - is also contentious, though it seems unlikely to have persisted after 500 AD, by which time the Anglo-Saxons had migrated to England and the Elbe Germanic tribes had settled in Southern Germany. A North Germanic language is any of several Germanic languages spoken in Scandinavia, parts of Finland and on the islands west of Scandinavia. ... West Germanic is the largest branch of the Germanic family of languages, including such languages as English, Dutch, and German. ... The tribes referred to as East Germanic constitute a wave of migrants who moved from Scandinavia into the area between the Oder and Vistula rivers between 600 - 300 BC. In historical times these tribes were differentiated as Goths, Burgundians and Vandals among others. ...

This grouping was proposed by Hugo Kuhn as an alternative to the older view of a Gotho-Nordic versus West Germanic division. The evidence for it is constituted by a range of common linguistic innovations in phonology, morphology, word formation and lexis in North and West Germanic, though in fact there is considerable debate about which innovations are significant. An additional problem is that Gothic, which provides almost the sole evidence of the East Germanic dialects, is attested much earlier than the other Germanic languages, with the exception of a few runic inscriptions. Phonology (Greek phonē = voice/sound and logos = word/speech), is a subfield of linguistics which studies the sound system of a specific language (or languages). ... Morphology is the following: In linguistics, morphology is the study of the structure of word forms. ... Wikipedia does not have an article with this exact name. ... This page is a candidate to be moved to Wiktionary. ... Besides its original meaning, of or relating to the Goths (Gothos, Getas), a Germanic tribe and thus the Gothic language and the Gothic alphabet, the word Gothic has been used to refer to distinctly different things: From a Renaissance perspective (originally Italian, gotico, with connotations of rough, barbarous), it conveyed...

Inscriptions are words or letters written, engraved, painted, or otherwise traced on a surface and can appear in contexts both small and monumental. ...

Among the common innovations cited as evidence for Northwest Germanic are:

• Proto Germanic /z/ > /r/ (e.g. Gothic dius; ON dȳr, OHG tior, OE dēor, "wild animal")
• The use of /ē²/ in the pretertite of Class VII strong verbs in North and West Germanic, while Gothic uses reduplication (e.g. Gothic haihait; ON, OE hēt, preterite of the Gmc verb *haitan "to be called")

Common innovations in North Germanic and Gothic, which therefore challenge the Northwest Germanic hypothesis, include: A strong inflection is an irregular inflection, in which the stem of a word changes. ... Reduplication, in linguistics, is a morphological process in which the root or stem of a word, or only part of it, is repeated. ...

• Proto Germanic /jj/, /ww/ > /ddj/, /ggw/ (e.g. Gothic triggwa, ON tryggva, OHG triuwe, "loyalty")

However, as long as Northwest Germanic is not regarded as proto-language, it is possible to harmonize these two hypotheses. An early close relationship between Nordic and Gothic dialects does not exclude a later similar relationship between remaining North and West Germanic groups, once the Gothic migration had started in the 2nd or 3rd century.

There are also common innovations in Old High German and Gothic, which would appear to challenge both the Northwest Germanic and the Gotho-Nordic groupings. However, these are taken to be the result of the known cultural contacts across the Alps in the 5th and 6th centuries, reflected in the Christian loanwords from Gothic into Old High German. The term Old High German (OHG, German: Althochdeutsch) refers to the earliest stage of the German language and it conventionally covers the period from around 500 to 1050. ...
