This paper is intended to present the results and highlight some of the problems of a preliminary exploration of the beginnings of a linguistic stratum in the placenomenclature of a region.1 For want of a better term this 'region' will be designated conventionally North East Scotland or the Scottish north-east, for our purposes, its heartland is understood to consist of Aberdeenshire , Banffshire and Moray but in addition the Mearns to the south of the Dee (now officially, though not historically, part of Aberdeenshire ) and the former county of Nairn to the west of Moray will also be included in this survey. There might have been considerable justification in extending our investigation southwards to include Angus because of its geographic proximity to and early historical associations with the Mearns but such expansion would have made what is, in its design, only an initial foray into an almost unexplored toponymic field of study much less manageable on the one hand, and would detract from, or even distort, our intended concentration on what is usually perceived as the Scottish North East proper, on the other. The focal urban area of Angus is, after all, Dundee, and not Aberdeen. It must nevertheless be admitted that there is a certain arbitrariness about the concept of the 'North East' employed in this study and that the 'region' as a whole is not as cohesive as would have been desirable. Like the rest of Scotland, its north-eastern parts are, in contrast to the emigrations of more recent centuries, pre-historically a region of immigrants, though they do not reflect all the waves that reached the Scottish shores in the last 3000 years or so in their linguistic stratification. As is to be expected, the least tangible of these strata are often the earliest ones since all we have to go by is toponymic, especially hydronymic, evidence. This consists of two distinct kinds which may have existed sequentially or simultaneously. In the first place, Ptolemy's 'map' of Scotland records on the basis of their latitude and longitudes nver names like Loxa, Tuesis and Caelis (for Kailos), all of them seemingly applying to water courses draining into the Moray Firth.2 In spite of several scholarly attempts3 and others not so scholarly, identifying, for example, the Loxa with the Lossie, and the Tuesis with the Spey, none of these can be uncontroversially matched with any of the rivers and their names, as we have them today, either by location or by linguistic form. In addition, there is the name of the major river in the more westerly areas of the region, the Spey, which has never been satisfactorily explained4 and may also belong to a stratum of river names the linguistic origins of which are unknown to us. 5 Secondly, there are some equally ancient river names, like the Nairn, the [Find]horn, the [Dev]eron, and possibly also the [Auld]ear« which can be associated with a pre-Celtic Indo-European stratum, such as the socalled Old European hydronymy of the European Bronze Age in which we find several identical equivalents.6 The oldest properly identifiable place names in the north-east belong to a p-Celtic
