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)

cen-
see, behold
cen- ("k")vb. "see, behold", future tense cenuva ("kenuva") "shall see" in Markirya. Imperative cena ("k"), VT47:31.Also #cen = noun "sight" as the final element of some nouns (*apacen, tercen, q.v.) Compare the root KHEN-, KEN-, KYEN- "look at, see, observe, direct gaze" (VT45:21)
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".
a-
see
a- (2) a prefix occurring in the Markirya poem (Tolkien first used na-, then changed it). It may be prefixed to verbal stems following a noun that is the object of sense-verbs like "see" and "hear" when the verb it is prefixed to describes what happens to this noun, as in man cenuva lumbor ahosta[?] (changed from na-hosta), "who shall see the clouds gather?" (hosta = "gather").
ala
after, beyond
ala (5) prep. "after, beyond" (MC:221, 214; however, LotR-style Quenya has han and pella "beyond" and apa "after")
apo
after
apo prep. ?"after" (see apa #1) (VT44:36)
tunta-
see, notice, perceive
tunta- "see, notice, perceive", pa.t. túne (QL:95)
véla
verb. see
véla (2) vb. "see" (Arct); present/continuative tense of a verbal stem #vel-? The context of the sentence where it occurs ("till I see you next") suggests that this is "see" in the sense of "meet".
>> yomenië
cata
after
cenya
verb. see, perceive
epe
after
As suggested by Helge Fauskanger (QQ/apacenyë), the literal meaning of this word is “after-sight”, that is knowledge of that which come after.
