Well, insofar as and are concerned, the inflectional 'root' found in the genitive singular of a noun, or in one of the principal parts of a verb, is usually referred to in textbooks and other didactic materials as the stem.eldin raigmore wrote: ↑24 Jul 2018 03:11 It is beginning to seem to me, that the term “root”, when discussing the diachronic processes of language evolution, and the genetic relatedness of languages in the same family, means something different, from the term “root”, when discussing the synchronic processes of inflection and morphological derivation, and suchlike morphological processes.
So, or not so?
But, certainly, at least as for as and verbs go, the principal parts can each have, as the main formant of their respective stems, different grades of a former Proto-Italic or PIE roots.
