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 pá, pa (q.v.) mentioned by Tolkien in the sense of apa #2. Another variant gives apa, pá "on (above but touching)" (VT49:18).
pá, 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 pá (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, pá 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)
