-nten ending for dual instrumental (Plotz)
Quenya
-ntë
suffix. they
-ntë
they
-nten
-nten
-ltë
they
-ltë, 3rd person pl. pronominal suffix, "they" (VT49:51; cariltë "they do", VT49:16, 17). It alternates with -ntë in Tolkiens manuscripts (VT49:17, 57). In his early material, the ending also appears as -lto, occurring in Fíriel's Song (meldielto "they are beloved" and cárielto "they made"), also in LT1:114: tulielto "they have come" (cf. VT49:57). Compare -lta, -ltya as the ending for "their".
-ltë
suffix. they
-nen
most nouns have an instrumental in -nen
-nen instrumental ending (pl. -inen, dual -nten, partitive pl. -línen). Attested in ambartanen, lírinen, lintieryanen, súrinen, parmanen; see ambar (#2), lírë, lintië, súrë, parma. Tolkien noted that "most nouns have an instrumental in -nen" (PE17:62), a wording suggesting that the form of the ending may vary; given the normal development ln > ld, it is possible that it would appear as *-den when added to a noun in -l (*macilden "with a sword").
-nta
their
-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).
-nta
suffix. their
-ttë
suffix. themselves
-ttë
they
-ttë (1) "they", dual 3rd person pronominal ending ("the two of them") (VT49:51), replacing (also within the legendarium) the older ending -stë (which was later used for the second person only). This older ending -stë corresponds to a possessive ending -sta "their" (VT49:16), but this was presumably likewise altered to *-tta as the new ending for dual "their" = "of the two of them".
intë
themselves
intë *"themselves", 3rd person pl. reflexive pronoun, e.g. *i neri tirir intë, "the men watch themselves". Intë is derived from earlier imte(VT47:37). Conceivably intë* is only used for "themselves" with reference to persons; impersonal "themselves" ought to be inta or intai, compare ta #3, tai #2. A form intai might however have evolved into intë by the Third Age (like pl. adjectives in -ai later came to end in -ë), thus converging with the "personal" form.% In an earlier source, Tolkien listed intë as an emphatic pronoun "they", 3rd person plural (VT49:48, 49); compare the pronominal ending -ntë. The word intë** (derived from inde via inze, an unusual development in Quenya) also appears as a candidate 2nd person singular polite form (VT49:49).
intë
pronoun. themselves
-lta
their
-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).
-lto
they
-lto, "Qenya" pronominal ending "they"; see -ltë
-ntya
their
-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).
-twa
their
-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)
attat
2 fathers or neighbours
-t (1) dual ending, on nouns denoting a _pair of something: attat "2 fathers or neighbours" (VT48:19; see _atto), máryat "her (pair of) hands" (Nam), siryat "two rivers" (VT47:11), ciriat "2 ships" (Letters:427 read ciryat as in the Plotz Letter?), maquat "group of ten" (from maqua, meaning among other things "group of five") (VT47:7), nápat "thumb and index as a pair" (VT48:5), also compare met "us two" as the dual form of me "us" (Nam, VT47:11). Other dual endings known from the Plotz letter: genitive -to, possessive -twa, dative -nt, locative -tsë, allative -nta, ablative -lto, instrumental -nten, plus -tes as a possible short locative. It may be that these endings only apply to nouns that would have nominative dual forms in -t, and that nouns preferring the alternative dual ending -u would simply add the otherwise "singular" case endings to this vowel, e.g. *Alduo rather than ?Alduto as the genitive form of "Two Trees" (Aldu). The ending -t is also used as a verbal inflection, corresponding to pl. -r (elen atta siluvat**, "two stars shall shine", VT49:45; the verb carit** "do" would also be used with a dual subject, VT49:16; cf. also the endings listed in VT49:48, 50).
ta
they, them
ta (3) pron. "they, them", an "impersonal" 3rd person pl. stem, referring "only to 'abstracts' or to things (such as inanimates) not by the Eldar regarded as persons" (VT43:20, cf. ta as an inanimate Common Eldarin plural pronoun, VT49:52). Compare te, q.v. The word ta occurring in some versions of Tolkien's Quenya Lord's Prayer may exemplify this use of ta as an "impersonal" plural pronoun: emmë avatyarir ta** "we forgive them" (VT43:8, 9; this refers to trespasses, not the trespassers). However, since Tolkien also wanted ta to mean "that" (see #1 above), he may seem to be somewhat dissatisfied with ta "they, them", introducing variant forms like tai (VT49:32) to free up ta as a sg. pronoun. In one document, tai was in turn altered to te (VT49:33), which could suggest that the distinction between animate and inanimate "they, them" was abandoned and the form te (q.v.) could be used for both. In some documents, Tolkien seems to use tar as the plural form (VT49:56 mentions this as an uncertain reading in a source where the word was struck out; compare ótar under ó**-).
tai
they, them
tai (2) pron. "they, them", 3rd person pl., used with reference to inanimates rather than persons or living things (VT49:32, see ta #3 above). Perhaps to avoid the clash with tai "that which", the pronoun tai "they, them" was altered to te in at least one manuscript (VT49:33), so that it would merge with the pronoun used of living beings and the distinction between animate and inanimate would be abandoned (see te).
te
they, them
te pron. "they, them", 3rd person pl. (VT49:51, LotR3:VI ch. 4, translated in Letters:308). The pronoun te represents an original stem-form (VT49:50). Dative ten, téna or tien "for them, to them" (q.v.) Stressed té (VT49:51). Ótë "with them", q.v. VT43:20 connects te "them" with a discussion of Common Eldarin pronominal stems (ca. 1940s), where te is the "personal" 3rd person pl. stem, referring to persons rather than abstracts or inanimates (which are denoted by ta instead; see, however, the entry ta #3 regarding the problems with this form, and the hints that te may possibly be used with reference to inanimates as well)). Also consider the reflexive pronoun intë "themselves", the final element of which is apparently this pronoun te; see also tú for the dual form.
toi
they
toi pron. "they" (FS; replaced by te in LotR-style Quenya?)
tú
they, them
tú pron. "they, them", 3rd person dual ("the two of them"), both "personal and neuter" (the pronoun can be used of persons and things alike). (VT49:51) Tolkien also considered tet for the same meaning, listing it alongside tú in one source (VT49:56), but this form was apparently abandoned.
-ntë "they", pronomimal ending, inflexion of 3rd person plural when no subject is previously mentioned (CO; see also VT49:49). This ending competes with -ltë (q.v.) in Tolkiens conception (VT49:57; for "they do", both carintë and cariltë are attested, VT49:16 vs. 17). The corresponding pronominal possessive suffix appears as -ntya or -nta in various sources.
