Аннотация:This paper is the third part in a series of studies that present additions to the corpus of etymological comparisons between the Uralic languages, drawing data from all the major branches of the language family.It includes both previously unnoticed cognates that can be added to already established Uralic cognate sets, as well as a few completely new reconstructions of Uralic word roots.In this third part new Uralic etymologies for the following Mari words are discussed: MariE j me-, MariW jǝme-'go numb' (< PU *jämä-), MariE jičke-, MariW jǝčke-'pick, pluck, pull' (< PU *ńičkä-), MariE wüt-kow, MariW koe, ko 'wave' (< PU *kompa), MariE lewe, MariW liwe 'warm' (< PU *lämpi), MariE nöńča-'shape, form' (< PU *ń nča-/*ńanča-'stretch'), MariE lüδa-, MariW lüδä-'be afraid' (< PU *l dV-), MariE p ze-, MariW pǝze-'hold, cling to' (< PU *pitä-), MariE šuma-, MariW š ma-'become tired, languish' (< PU *śoma-), MariE šüδa-, MariW šüδä-'clear (wood, road, field, etc.)' (< PU *s nti-), MariE tüž, tüjüž, MariW tüž 'pregnant (of animals)' (< PU *tejniš).The principles of reconstruction and the citation of lexical material are explained in the first paper of the series (Luobbal Sámmol Sámmol Ánte 2013).The reconstruction of Proto-Mari vocalism applied in this paper is argued in more detail by Luobbal Sámmol Sámmol Ánte (2014).
