Following this preliminary investigation, 1 would argue that Margaret's use of Scots, or, probably more accurately, varied incorporation of Scots features in her writing system (and probably her speech) would have reflected her experience not just as any individual moving across dialectal boundaries, but specifically as a late medieval/early modern queen writing, and sometimes moving physically across what is today the most significant isogloss in Britain (see e.
Considered one of the "key concepts" of post-colonial studies and a rhetorical figure for radical alterity, cannibalism is recognized as a cultural isogloss on which the "separation of the 'civilized' and the 'savage'" hinges (Ashcroft 29-31).
Certainly, isoglosses can be helpful to show the limits of individual features, so long as it is made clear that an isogloss is an approximate boundary for that feature alone, and therefore makes a "generalization about the evidence" (Kretzschmar 2009: 69).
This may be an important isogloss that distinguishes northern Domari from southern Domari, since no reference to it is made neither by Macalister nor by Matras.
In Central Franconian, there is a distinctive opposition between a falling tone 1 and a stretched tone 2 that seems to be reversed in a strip of land along the southeastern border, which is formed by the "thick bundle of isoglosses separating Central Franconian from Rhine Franconian, the most characteristic one being the isogloss between the pronoun dat 'that' to the northwest and das to the southeast" (de Vaan 1999: 41).
Post-vocalic /r/ is a sociolinguistic variable in New York City, in England it defines basically a large-scale dialect isogloss, and in many parts of the American Midwest it shows little variation of any sort.
It would appear that whatever the explicit ideology, lines are not clearly drawn between "Judaism" and "Christianity," but at least one highly significant isogloss (that is, highly significant for the Rabbis, for whom it marks the difference between orthodox and heretic, just as it does for Justin and the Pseudo-Clementines); the line is between Jew and Jew, between Christian and Christian, thus marking a site of overlap and ambiguity between the two "religions" that the texts are at pains to construct.
But however interesting the isogloss is to the historian of languages, it gives only limited help to the student of Greek realities.
Johnson and Fine (1985) studied gender differences in the uses and perceptions of obscenity, reporting that their respondents saw this type of language as "an isogloss marking the speech communities of males and females" (p.
Wiik and Lehiste, who have studied the matter, conclude on this isogloss (1968 : 573-574): "In the type of Finnish that does not use a half-long vowel, quantity appears to function primarily on a segmental level.
The results of the analysis are presented in a detailed series of isogloss bundles along with specific figures and percentages for numbers of features shared or not shared (pp.
Unlike what we observe in the Slavic and Kartvelian language families, finally, Ossetic is the only Iranic language hating developed this kind of derivational-like grammatical category (Edel'man 2002: 127); hence, Abaev [1965/1995: 343-354] and Edel'man [2002: 127] consider the aspectual value of preverbs, together with the Genitive-Accusative case marking on direct objects, to be a very old grammatical isogloss shared by Ossetic and Russian, which goes back to early contacts between Scythian and Eastern Slavs (7).
