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.

Eru
the oneEru 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).

selda
childselda 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
childseldo noun (meaning not quite clear, likely the masculine form of seldë "child", hence *"boy") (SEL-D, VT46:13, 22-23)
seldë
childseldë 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.
A name for Elves and Men as children of Eru (God), frequently appearing in its plural form Eruhíni (Let/189, MR/320, WJ/403). It is a compound of Eru “God” and a suffixal form -hin of hína “child” (SA/híni).
Conceptual Development: This name first appeared in the tales of the Fall of Númenor from the 1940s as the Adûnaic word #Êruhin, attested only in its plural forms Êruhîn(im) (SD/247-8, 311). See that entry for further discussion of its early history.
