aulëonnar
collective name. Children of Aulë
erusēn
collective name. Children of God
A variant form of Eruhin appearing in a few places (MR/423, RGEO/66). Its final element may be related to the root ᴹ√SEL(D) “child”. The similar word Melkorsēni “Children of Melkor” appears to have the same final element (MR/423). It is possible that Tolkien introduced the variation so that the Sindarin form would be S. Eruhîn, resembling the earlier Adûnaic form Ad. Êruhîn.
melkorohíni
collective name. Children of Melkor
Name of the Orcs as children of Melkor, a parody of the name Eruhíni for Elves and Men as children of Eru (MR/416). It is a compound of Melkor and the plural form of hína “child”. It also appeared in the form Melkorsēni (MR/423), similar to the variant form Erusēn(i) of Eruhíni, but the etymology of this form is unclear. Both versions of this name imply a stem form Melkoro- for Melkor, but this is contradicted by other examples. See the entry on Melkor for further discussion.

hína
noun. child
A word for “child” derived from the root √KHIN (PE17/157; WJ/403), most notably an element in Eruhíni “Children of God”, a term for Elves and Men as the children of Eru. This word illustrates that hína has an abnormal plural form: híni rather than the expected ✱✱hínar. A variant hina with a short i was “only used in the vocative addressing a (young) child, especially in hinya (< hinanya) ‘my child’ (WJ/403)”.
Conceptual Development: The term Êruhîn “Children of God” first appeared as an Adûnaic word in the 1940s (SD/247-8, 358), later adapted as Quenya Eruhíni and Sindarin Eruchîn, which seems to be the source of Q. hína and S. hên “child”. At one point Tolkien coined masculine and feminine variants Q. hindo and Q. hindë, but they were deleted (PE17/157). Tolkien often used an alternate Quenya form sén (MR/423; UT/274; RGEO/66), perhaps out of a desire to have a Sindarin form Eruhîn that was closer to the original Adûnaic form. This variant continued to appear as late as 1969, where sén was written below Eruhíni as a variant form in Late Notes on Verbs (LVS: PE22/158).
hína
child
hína noun "child", also hina used in the vocative to a (young) child (also hinya "my child", for hinanya) (WJ:403). Pl. híni (surprisingly not **hínar) in Híni Ilúvataro "Children of Ilúvatar" (Silmarillion Index); dative hínin in VT44:35. In compounds -hin pl. -híni (as in Eruhíni, "Children of Eru", SA:híni). According to one source, the word is hín(i) and solely plural (PE17:157), but this is obviously contradicted by some of the sources quoted above.
onna
noun. child, child, *offspring; [ᴹQ.] creature
A word for “child” appearing in various late notes and phrases (NM/31; PM/391; VT49/42), derived from the root √NŌ/ONO “beget, be born” and once appearing in a variant form onwe (PE17/170). Giving its derivation, its actual meaning may be closer to “✱offspring”, as first suggested to me by Tamas Ferencz.
Conceptual Development: In The Etymologies of the 1930s, ᴹQ. onna was instead glossed “creature”, though it was still derived from the root ᴹ√ONO “beget” (Ety/ONO).

onwë
noun. child
selda
child
selda adj.?noun? (meaning not clear, related to seldë "child" (meaning changed by Tolkien from "daughter") and seldo "boy". Thus selda may be an adjective "childlike", since -a is a frequent adjectival ending. Alternatively, as suggested in VT46:13, selda may be a neuter noun "child", corresponding to masc. seldo "boy" and fem. seldë "girl" (before Tolkien changed the meaning of the latter to "child"). (SEL-D, cf. VT46:22-23)
seldo
child
seldo noun (meaning not quite clear, likely the masculine form of seldë "child", hence *"boy") (SEL-D, VT46:13, 22-23)
seldë
child
seldë noun "child" (meaning changed by Tolkien from "daughter"; in his later texts the Quenya word for "child" is rather hína, and the final status of seldë is uncertain. See also tindómerel.) (SEL-D, VT46:13, 22-23) In one late source, Tolkien reverts to the meaning "daughter", but this may have been replaced by anel, q.v.
Eru
the one
Eru divine name "the One" = God (VT43:32, VT44:16-17), "the One God" (Letters:387), a name reserved for the most solemn occasions (WJ:402). Often in the combination Eru Ilúvatar, "Eru Allfather" (cf. MR:112). Genitive Eruo (MR:329, VT43:28/32), dative Erun (VT44:32, 34). The adjectival form Eruva "divine" (Eruva lissëo "of divine grace", VT44:18) would be identical to the form appearing in the possessive case. Compound nouns: Eruhantalë "Thanksgiving to Eru", a Númenórean festival (UT:166, 436), Eruhin pl. Eruhíni "Children of Eru", Elves and Men (WJ:403; SA:híni, cf. _Eruhîn _in Letters:345), Eruion *"son of God" (or "God the Son"?) (VT44:16), Erukyermë "Prayer to Eru", a Númenórean festival (UT:166, 436), Erulaitalë "Praise of Eru", a Númenórean festival (UT:166, 436), Eruamillë "Mother of God" (in Tolkien's translation of the Hail Mary, VT43:32, see also VT44:7), Eruontari, Eruontarië other translations of "Mother (Begetter) of God" (VT44:7, 18), Erusén "the children of God" (RGEO:74; this is a strange form with no plural ending; contrast the synonym Eruhíni.) #Eruanna and #erulissë, various terms for "grace", literally "God-gift" and "God-sweetness", respectively (VT43:29; these words are attested in the genitive and instrumental case, respectively: Eruanno, erulissenen).
Ilúvatar
all-father
Ilúvatar masc. name "All-father", God (SD:401, FS, IL; Ilúv-atar, ATA, Iluvatar with a short u, SD:346). Often in combination with the divine name as Eru Ilúvatar, "Eru Allfather", cf. MR:112. "Qenya" genitive Ilúvatáren "of Ilúvatar" in Fíriel's Song, LR:47 and SD:246, the genitive ending is -en instead of -o as in LotR-style Quenya. Cf. the later genitive Ilúvataro in the phrase Híni Ilúvataro (see "Children of Ilúvatar" in the Silmarillion Index)
Melkor
mighty-rising
Melkor (spelt Melcor in VT49:6, 24, MR:362), masc. name: the rebellious Vala, the devil of the Silmarillion mythos. Older (MET) form Melkórë "Mighty-rising" (hence the interpretation "He that arises in power"), compare órë #2. Oldest Q form *mbelekōro (WJ:402). Ablative Melkorello/Melcorello, VT49:7, 24. Compounded in Melkorohíni "Children of Melkor", Orcs ("but the wiser say: nay, the slaves of Melkor; but not his children, for Melkor had no children") (MR:416). The form Melkoro- here occurring may incorporate either the genitive ending -o or the otherwise lost final vowel of the ancient form ¤mbelekōro. For Melkors later name, see Moringotto / Moricotto (Morgoth) under mori-.
indi
offspring of the valar
indi pl. noun, apparently a name of Men, hardly valid in Tolkien's later Quenya (LT2:343). Compare, however, the final element of Valarindi "Offspring of the Valar", suggesting that #indi can be used for "offspring" (the Quenya word is apparently plural). It may be that in Valarindi, a h has dropped out following r, and that the independent word would be *hindi (as a variant of -hín, -híni "children").
onna
creature
onna noun "creature" (ONO), "child" (PE17:170), also translated "child" in the plural compound Aulëonnar "Children of Aulë", a name of the Dwarves (PM:391), and apparently also used = "child" in the untranslated sentence nai amanya onnalya ter coivierya ("k") "be it that your child [will be] blessed thoughout his/her life" (VT49:41). The form onya (q.v.), used as a vocative "my child", is perhaps shortened from *onnanya.
#sén collective (?) noun "children", isolated from Erusén "the children of God" (RGEO:74, VT49:35). The word would seem to be a collective, since it has no plural ending.
