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".

apacenyë is translated "foresight" in MR:216; yet the context and the form of the word itself clearly indicates that it is not a noun but actually the pl. form of an adjective *apacenya *"of foresight". The noun "foresight" is almost certainly apacen; cf. tercen "insight". (MR:216) The literal meaning of apacen is "aftersight", sc. knowledge of that which comes after. [Essi] apacenyë** "[names] of foresight", prophetic names given to a child by its mother (MR:216)
