apa

on

apa (2) prep. denoting "on" with reference to contact of surfaces, especially vertical surface (in the sense in which a picture hangs on a wall). Apa is said to have this meaning in various Tolkien manuscripts (VT44:26), but apa is also used for "after" (see apa #1 above), and the two were probably never meant to coexist in a single variant of Quenya. The clash may be avoided by consistently using the variants , pa (q.v.) mentioned by Tolkien in the sense of apa #2. Another variant gives apa, "on (above but touching)" (VT49:18).

on

, pa (1) prep. "on" with reference to contact of surfaces, especially vertical surface (in the sense in which a picture hangs on a wall); also used = "touching, as regards, concerning" (VT44:26). Another variant gives (and apa) with the meaning "on (above but touching)". (2) Variants of apa "after" (VT44:36), which preposition is in one source also ascribed the first meaning here discussed. For Neo-Quenya purposes, and pa may be used for "on" or "concerning", whereas apa is used for "after" (see entries for apa #1 and #2), or pa may also be seen as a shorter form of apa "after", as in the phrase yéni pa yéni *"years upon years" (VT44:36)

* -nud

preposition. on

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”.
