(i choneg, o choneg), pl. honig (i chonig), also used as a play-name for the middle finger. (VT47:6, 16-17) 2) In older sources Tolkien listed different ”Noldorin” words for ”brother”: muindor (i vuindor), analogical pl. muindyr (i muindyr). Archaic/poetic †tôr (i** dôr, o thôr, construct tor), pl. teryn (i** theryn), coll. pl. toronath. In ”Noldorin”, the pl. was terein. 3) “Brother” in extended sense of “relative”: gwanur (i ’wanur) (kinsman, also kinswoman), pl. gwenyr (in gwenyr). Note: a homophone of the sg. means ”pair of twins”.
hanar
noun. brother
hanar
noun. brother
A word for “brother” coined by Tolkien in notes on Eldarin Hands, Fingers and Numerals from the late 1960s, based on the root √KHAN of the same meaning and replacing the archaic form of the word †hawn (VT47/14). Remnants of this archaic form can be seem in the diminutive/affectionate form honeg “[little] brother” (VT48/6); Tolkien considered and apparently rejected alternates of the diminutive: honig and hanig (VT47/14; VT48/17).
Conceptual Development: The Etymologies of the 1930s had N. tôr “brother” from the root ᴹ√TOR (Ety/TOR), and the Gnomish Lexicon of the 1910s had G. hethos “brother” from the early root ᴱ√HESE [HEÞE] (GL/48-49; QL/40). See those entries for discussion.

hanar
brother
1) hanar (i chanar, o chanar), pl. henair (i chenair) (VT47:14). A more archaic term is *haun (spelt ”hawn” in source) (i chaun, o chaun), pl. hoen (i choen), coll. pl. honath.
hanar

(i chanar, o chanar), pl. henair (i chenair) (VT47:14). A more archaic term is ✱haun (spelt ”hawn” in source) (i chaun, o chaun), pl. hoen (i choen), coll. pl. honath.
Primitive elvish
khan
root. brother
A root for “brother” that Tolkien introduced in notes on finger-names from the late 1960s as a companion to √NETH “sister” (VT47/14, 26, 34). It conflicts with, and possibly replaces, earlier uses for √KHAN such as √KHAN “back” in notes from around 1959 serving as the basis for the prefix Q. han- in hanquenta “answer” (PE17/166). The root ᴹ√KHAN also appeared in The Etymologies of the 1930s glossed “understand, comprehend”, with various derivatives in both Quenya and Noldorin of similar meaning (Ety/KHAN).
It is unlikely that all these uses of √KHAN coexisted, but I think at a minimum both √KHAN “brother” and ᴹ√KHAN “understand, comprehend” should be retained for the purposes of Neo-Eldarin, as the latter has no good replacements in Tolkien’s later writing. As for hanquenta “answer”, it might be reinterpreted as “a saying providing understanding”, and so be derived from ᴹ√KHAN “understand”.
Telerin
hanna
noun. brother
háno
noun. brother
Quenya
hanno
brother
hanno noun "brother" (a colloquial form, cf. háno), also used in children's play for "middle finger" (VT47:12, 14, VT48:4, 6)
háno
brother
háno noun "brother", colloquially also hanno (VT47:12, 14). It is unclear whether Tolkien, by introducing this form, abandoned the older (TLT) word toron (q.v.)
háno
noun. brother
A word for “brother” coined by Tolkien in notes on Eldarin Hands, Fingers and Numerals from the late 1960s, based on the root √KHAN of the same meaning (VT47/14). It had a diminutive/affectionate variant hanno used as a play name for the middle finger in several places in these notes (VT47/12; VT48/6).
Conceptual Development: The Etymologies of the 1930s had ᴹQ. toron “brother” from the root ᴹ√TOR (Ety/TOR), and the Qenya Lexicon of the 1910s had ᴱQ. herendo “brother” from the early root ᴱ√HESE (QL/40). See those entries for discussion.
onóro
brother
onóro noun "brother" (of blood-kinship) (TOR, NŌ (WŌ) )
otorno
brother, sworn brother, [male] associate
otorno noun "brother, sworn brother, [male] associate" (TOR, WŌ). Cf. osellë.
toron
brother
toron (torn- as in pl. torni) noun "brother" (TOR; a later source gives háno, hanno [q.v.] as the word for "brother", leaving the status of toron uncertain)
Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
Gnomish
hethos
noun. brother
Early Quenya
herendo
noun. brother
A word for “brother” in the Qenya Lexicon of the 1910s with numerous variants: herendo or herēro, hestaner, and hesta(noi)nu, all based on the early root ᴱ√HESE that was the basis for “brother” and “sister” words (QL/40). Of these Tolkien said herendo/herēro was the “ordinary word”, and herendo appeared in the Poetic and Mythological Words of Eldarissa (PME/40).
heréro
noun. brother
hestaner
noun. brother
hestanoinu
noun. brother
hestanu
noun. brother
Qenya
toron
noun. brother
A noun for “brother” in The Etymologies of the 1930s derived from the root ᴹ√TOR of the same meaning, with a somewhat irregular plural torni (Ety/TOR). Its stem form is torn-, since with most inflected forms the Quenya syncope comes into play and the second o is lost.
Neo-Quenya: In notes from the late 1960s, Tolkien introduced a new word háno for “brother” (VT47/14). However, I think toron might be retained to mean a “metaphorical brother”, a close male associate who may or may not be related by blood, as with such words as melotorni “love-brother, ✱close male friend” or ᴹQ. otorno “sworn brother”. In this sense, háno would be limited to biological relationships, but toron would refer to brotherly (or brother-like) affection.
Old Noldorin
toron
noun. brother
wator
noun. brother
Middle Primitive Elvish
tor
root. brother
Tolkien gave this root in The Etymologies of the 1930s as ᴹ√TOR “brother” with derivatives like ᴹQ. toron and N. tôr of the same meaning (Ety/TOR). Hints of the roots continued use appear in the 1959 term Q. melotorni “love-brothers” for close male friends (NM/20). In notes from the late 1960s, Tolkien gave Q. háno and S. hanar as the words for “brother”, both from the root √KHAN. Nevertheless, I think it is worth retaining ᴹ√TOR to represent more abstract notions of “brotherhood” for the purposes of Neo-Eldarin, for “metaphorical” brothers as opposed to Q. háno/S. hanar for brothers by blood.
An (archaic) word for “brother” in The Etymologies of the 1930s derived from the root ᴹ√TOR of the same meaning, with an irregular plural terein (Ety/TOR). In ordinary speech, it was replaced by muindor, with an initial element muin “dear”.
Neo-Sindarin: In notes from the late 1960s, Tolkien introduced a new word hanar for “brother” (VT47/14). However, I think †tôr and related words might be retained to mean a “metaphorical brother”, a close male associate who may or may not be related by blood, as with such words as gwador “(sworn) brother, associate”. In this paradigm, I would assume muindor still refers to a brother by blood, with an added connotation of strong affection.
