√RAT² root. “tower up”
The extended root √ARAT “good, excellent, noble” appeared in 1957 Quenya Notes (QN) as an extension of √AR “beyond, further than”, and was principally used for the adjectives Q. ar(a)ta, S. arod/raud “noble” and elaborations thereof (PE17/147). In Definitive Linguistic Notes (DLN) from 1959 it was instead given as √RAT “tower up”, serving as the basis for the same set of words (PE17/186). In any case, all these seem to be variants of √RĀ/ARA “noble”; see that entry for details.
