Ad. *-nud prep. “on” (Category: Up, Above, Over)
A preposition attested only in the phrase “on us” in the Lament of Akallabêth, changing through the drafts as nēnum >> nēnu >> nēnud (SD/247, 312). Most authors identify -nud as the prepositional element (AAD/20, LGtAG, NBA/14), perhaps related to Q. nu “under”. If so, it may be a derivative of the Elvish roots √NŪ/UNU “under” or √NDU “down”, with a semantic shift to the meaning “on”.
