diasystemn.

1954 U. Weinreich in Word 10 390 Structural linguistic theory now needs procedures for constructing systems of a higher level out of the discrete and homogeneous systems that are derived from description and that represent each a unique formal organization of the substance of expression and content. Let us dub these constructions ‘diasystems’... A ‘diasystem’ can be constructed by the linguistic analyst out of any two systems which have partial similarities.

1963 T. A. Sebeok in J. A. Fishman Readings Sociol. of Lang. (1968) 24 Crows free to migrate between the two regions construct a diasystem which enables them to understand both local dialects.

1968 Language 44 485 But all languages and all dialects are dia-systems as well, so this does not constitute a special characteristic of proto-languages.

1982 Amer. Speech 57 14 What we see, then, is an attempt to define the limits of a diasystem which is open to considerable vagueness and arbitrary delimitation when examined in detail.

1981 Amer. Speech 1977 52 227 A diasystematic base from which all observable dialect variants could be derived.

1976 Language 52 267 T[rudgill] posits a model which includes a diasystemic phonological system,..morphological alternation rules,..phonological realization rules, [etc.].

1977 Word 28 326 Before discussing the phonological similarities and differences among these dialects as they are brought into prominence diasystemically, I should like to describe briefly the importance of the Atlas Linguistique de la France in the history and development of dialect studies.
