hen (hend-, as in pl. hendi) noun "eye" (KHEN-D-E); possibly dual #hendu in hendumaica, q.v. Noun henfanwa "eye-screen, veil upon eyes" (PE17:176), adj. henulca "evileyed" (SD:68; cf. ulca).
Quenya
hen
noun. eye
hen
eye
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 occasionally used an alternate Quenya form sén (MR/423; UT/274), 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).
seldo
child
seldo noun (meaning not quite clear, likely the masculine form of seldë "child", hence *"boy") (SEL-D, VT46:13, 22-23)
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
child
onwë noun "child" (PE17:170)
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)
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.
sén
noun. child
The Quenya word for “eye”, derived from the root √KHEN for eye-words (PE17/187; Ety/KHEN-D-E) and with stem-form hend- given its dual hendu (WJ/337).
Conceptual Development: This word first appeared as ᴱQ. hen in The Qenya Phonology of the 1910s, derived from primitive ᴱ✶þχe-ndǝ and appearing beside ᴱQ. sé “eye, pupil” < ᴱ✶þeχē (PE12/21). Hen (hend-) “eye” appeared in the Qenya Lexicon though it was marked “†” for archaic (QL/40), and ᴱQ. hend- also appeared in the contemporaneous Gnomish Lexicon as the cognate of G. hen “eye” (GL/48). ᴱQ. hen appeared regularly in documents from the 1920s (PE13/147; PE14/43, 76; PE16/136), although in the Early Noldorin Grammar of the 1920s ᴱQ. sinda was given as the cognate of ᴱN. hen(n) “eye” (PE13/122). The form ᴱQ. sinda seems to have been a transient idea.
A lengthy declension of ᴹQ. hen “eye” appeared in documents from the early 1930s (PE21/52) and in The Etymologies of the 1930s it was based on a new the root ᴹ√KHEN-D-E “eye” (Ety/KHEN-D-E). In both these documents, inflected forms indicate a stem form of hend-. Thus this word and its stem were quite stable in Tolkien’s mind, though he did alter its root from early ᴱ√SEHE [ÞEHE] to later √KHEN.
