agar
noun. blood
A noun for “blood” appearing as an element in the name Agarwaen (S/210). It’s later etymology is unclear.
Conceptual Development: An earlier iteration of the name was N. {Iarvael >>} N. Iarwath “Blood-stained” from The Etymologies of the 1930s, where the element was N. iâr “blood” from the root ᴹ√YAR of the same meaning (Ety/YAR). Tolkien considered changing the root to ᴹ√YOR and the Noldorin form to iûr (EtyAC/YAR). This seems to be transient idea, since the name Iarwaeth “Bloodstained” appeared in the Grey Annals from the early 1950s (WJ/83) before ultimately being replaced by Agarwaen (WJ/142).
Neo-Sindarin: For purposes of Neo-Sindarin, I’d stick to the better-described sereg for “blood”.

root. blood
A root in Quenya Notes (QN) from 1957 given as the basis for the “blood” words Q. serke and S. sereg as well as the flower name S. seregon “blood of stone” (PE17/184), a flower name that also appeared (untranslated) in The Silmarillion (S/203). It may replace the root ᴹ√YAR “blood” from The Etymologies of the 1930s with derivatives like ᴹQ. yár and N. iâr of the same meaning, the later an element in the surname of Túrin: N. Iarwath “Blood-stain” (Ety/YAR). In later Silmarillion drafts, it became Iarwaeth (WJ/83) and then S. Agarwaen “Blood-stained”, the form it took in the published version of The Silmarillion (S/210). The etymology of S. agar- “blood” is unclear.
Neo-Eldarin: For purposes of Neo-Eldarin, I’d stick to √SEREK = “blood”.

Doriathrin
ôr
noun. blood
A noun for “blood” derived from the root ᴹ√YAR (Ety/YAR). Its cognates ᴹQ. yár and N. iâr indicates a primitive form ✱✶yār(ǝ) [jārǝ], where the vowel changed to [o] because of Ilkorin a-affection. Helge Fauskanger suggested instead that the primitive form was ✱✶yara because of the Quenya stem form yar-, with a lengthening of the vowel in the primitive monosyllabic form (AL-Ilkorin/ôr) @@@ examine further.
Early Quenya
hari
noun. blood
vísi
noun. blood
A noun appearing as vísi- “blood” in the Qenya Lexicon of the 1910s under the early root ᴱ√VIKI or ᴱ√VIT͡YI (QL/60). Its form might be explained by the Early Qenya sound changes ti > tsi > si (PE12/23).
Qenya
yár
noun. blood
A noun for “blood” in The Etymologies of the 1930s from the root ᴹ√YAR of the same meaning (Ety/YAR). Tolkien considered changing the root to ᴹ√YOR and the Quena form to yōr (EtyAC/YAR).
Conceptual Development: The word ᴱQ. hari “blood” from the Early Quenya Grammar (EQG) of the 1920s might be a precursor. It in turn was probably related to earlier ᴱQ. hara(nda) “flesh-meat” from Qenya Lexicon of the 1910s (QL/39).
Neo-Quenya: Since Tolkien changed its cognate from [N.] iâr to [S.] agar, this Quenya word is probably no longer valid, and for purposes of Neo-Quenya I recommend using the later word Q. sercë “blood” instead.
yór
noun. blood
yár (yar-, as in dat.sg. yaren) noun "blood"_ (YAR; the Silmarillion appendix gives _sercë instead. According to VT46:22, Tolkien introduced yór_ as a replacement form in the Etymologies itself.)_
