A neologism coined by Tamas Ferencz for “anus, arsehole”, a combination of cata “behind” and [ᴹQ.] assa and hence more literally “behind-hole”.

ala (5) prep. "after, beyond" (MC:221, 214; however, LotR-style Quenya has han and pella "beyond" and apa "after")
apa
after
apa (1) prep. "after" (VT44:36), attested as a prefix in apacenyë and Apanónar, q.v. Variant ep- in epessë, q.v.; see epë for futher discussion. (According to VT44:36, apa was glossed "after" and also "before" in one late manuscript, but both meanings were rejected.) See also apa # 2 below. For Neo-Quenya purposes, apa should probably be ascribed the meaning "after", as in our most widely-published sources (compare Apanónar, "the After-born", as a name of Men in the Silmarillion). Variants pa, pá (VT44:36), but like apa these are also ascribed other meanings elsewhere; see separate entry. Apo (VT44:36) may be yet another variant of the word for "after".
