-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).
-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).
-nya pronominal suffix, 1st person sg. possessive, "my" (VT49:16, 38, 48), e.g. tatanya "my daddy" (UT:191, VT48:17), meldonya "my [male] friend" (VT49:38), meldenya "my [female] friend" (Elaine inscription), omentienya "my meeting" (PE17:68), tyenya "my tye" (tye being an intimate form of "you"), used = "dear kinsman" (VT49:51, 56). This ending seems to prefer i as its connecting vowel where one is needed, cf. Anarinya "my sun" in LR:72, so also in hildinyar "my heirs". It was previously theorized by some that a final -ë would also be changed to -i- before -nya, but the example órenya "my heart [órë]" indicates that this is not the case (VT41:11).
-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).
ninya _possessive pron _occurring in Fíriel's Song, evidently meaning "my"; see indo-ninya. It may be derived from the dative form nin "for me" by adding the adjectival ending -ya. Compare menya, q.v.
