-wen "maiden" as suffix, a frequent ending in feminine names like Eärwen "Sea-maiden" (SA:wen). Early "Qenya" also has -wen, feminine patronymic "daughter of" (LT1:271, 273), but the patronymic ending seems to be -iel "-daughter" in Tolkien's later Quenya.
wendënoun. maiden, maiden, *virgin
The exact form and etymology of this word is unclear. In many places it is attested as wendë, but the later Quenya form would have been vendë as [w-] > [v-]. Its usual etymology was as a derivative of √WENED, but in some cases it was related instead to √GWEN. This fits the Sindarin form gwend, though the gw- could have been a separate development in that language.
-nta (2) possessive 3rd person pl. pronominal ending: "their" (VT49:17). Lintienta "their speed" (PE17:58), nassentar "their true-being[s]" (PE17:175). This ending corresponds to -ntë "they" (other versions of Quenya uses -ltë for "they" and hence -lta for "their"). Also -ntya, q.v. According to VT49:17, the ending -nta appears as -inta following a consonant (other sources point to -e- rather than -i- as the connecting vowel in such cases).
-twa 2) an pronominal possessive ending mentioned in one chart of pronouns, apparently "their" referring to two persons (VT49:16); this may be an ending used in colloquial Quenya rather than formal language (it is listed together with the endings -ya "his, her" and -rya "their", that are explicitly said to belong to colloquial Quenya) (VT49:16-17)
-ntya, possessive 3rd person pl. pronominal ending: "their" (VT49:17), corresponding to -ntë as the ending for "they". Besides -ntya the form -nta is also attested, but the latter clashes with the ending for dual allative. (Other variants of Quenya uses -lta for "their", corresponding to -ltë as the ending for "they".) According to VT49:17, the ending -ntya appears as -intya following a consonant (other sources point to -e- rather than -i- as the connecting vowel in such cases).
vendë < wendë noun "maiden" (WEN/WENED, VT45:16), "virgin" (in Tolkien's translations of Catholic prayers where the reference is to Mary; see VT44:10, 18). The form Véndë in VT44:10 seems abnormal; normally Quenya does not have a long vowel in front of a consonant cluster.
-lta (and -ltya), 3rd person pl. pronominal possessive suffix "their", alternating with -nta/-ntya in Tolkiens writings (VT49:16, 17), just as the ending -ltë "they" also has the variant -ntë. According to VT49:17, the ending -lta or -ltya will appear as -ilta, -iltya following a consonant; other sources rather point to -e- as the connecting vowel in such cases (VT49:17).
