nay
root. cause bitter grief or pain, cause bitter grief or pain, [ᴹ√] lament
nay
root. have opportunity, chance or permission; be allowed by circumstance [or] way of the world
A root appearing in Late Notes on Verb Structure (LVS) from 1969 as √NAYA “have opportunity, chance or permission; be allowed by circumstance [or] way of the world” giving a new etymology for Q. nai “it may be”.
Neo-Eldarin: For purposes of Neo-Eldarin, I would ignore this root since it conflicts with the much better established √NAY “grief, pain”, and would stick with the well established etymology of Q. nai “maybe, be it that” = Q. ná- + Q. i.
nayak
noun. goat
A primitive word for “goat” appearing in Common Eldarin: Noun Structure of the early 1950s, with masculine and feminine variants ✶najakō “he-goat” and ✶naikē “she-goat” (PE21/82). It might be an elaboration of √NAY “cause bitter grief or pain”, a root that was the basis for various “lament” words. This hypothetical relationship might be a later analog of the connection between early roots ᴱ√NYE(NE) “bleat” (the basis for “goat” words) and ᴱ√NYEHE “weep”; hat tip to Raccoon for suggesting this to me.
nay-

yan
root. wide, extensive, large, vast, huge; extend
A root Tolkien introduced in the late 1950s to serve as the basis for various “land” suffixes in Sindarin. The most detailed explanation appeared in a set of documents labeled “Changes affecting Silmarillion nomenclature”:
> The endings -ion, -ien, -ian(d) in place names. These have various origins. In Sindarin -ion is usually from -ı̯aun. This in origin is from yānā, √YANA-, extension of yā- (cf. YAGA, gap) “wide, large, extensive”. S iaun “roomy, wide, extensive” ... -iand (-ian) is from yandē “a wide region, or country” ... This was often used in plural of a single country (especially if it contained a varied topographical apsect) > iend, ien (PE17/42).
Thus all three suffixes -ian(d), -ien(d), -ion originate in the root √YAN. The suffix -ian(d) “land” (Beleriand) is the simplest, just a reduction of ancient -yandē. The suffix -ien(d) “lands” (Anórien) is a plural variant of -ian(d). The suffix -ion (Eregion) is S. iaun “wide, extension” used as a suffix (so perhaps = “✱extent”), becoming -ion because of the usual sound change whereby au become o in polysyllables.
In this same document, Tolkien also considered introducing a root √YŎNO “wide, extensive”, going so far as (temporarily) rejected the very well established word Q. yondo “son”. This √YON was blended with √YOD “fence, enclose”, and served as the basis for the suffix -ion, but Tolkien ultimately marked these notes with an “X” to reject them, perhaps because they only explained the suffix -ion, whereas √YAN could explain all three suffixes.
√YAN was mentioned in passing in other documents from this period, variously glossed “vast, huge” (PE17/99), “wide” (PE17/115), and “extend” (PE17/155), and in one place given a variant √YAD (PE17/115). In notes from December 1959 (D59) √YAN was contrasted with √ƷAN, the former meaning “wide” and the latter meaning “long”, both with the basic sense “extend” (PE17/115); see the entry on √HAN for further discussion.
Elvish words beginning with nai- seem to be associated with pain and grief for much of Tolkien’s live. This root first appeared as ᴱ√NAẎA “hurt, grieve” in the Qenya Lexicon, but Tolkien said its original form was probably ᴱ√ŊAH͡YA (QL/65). Under the entry ᴱ√NAẎA it had derivatives like ᴱQ. naike “pain”, ᴱQ. naira “dire, grievous”, and ᴱQ. naitya- “damage, hurt; put to shame, abuse”, but Tolkien linked it to augmented forms like ᴱQ. angayasse “miserable”, which were related to the name of the great chain ᴱQ. Angaino used to bind Melkor (QL/34). In the contemporaneous Gnomish Lexicon the root form was given as ᴱ√ŋaı̯ with derivatives like G. gaist “torment, oppression” and G. gaista- “oppress, cause great grief to” (GL/37).
In The Etymologies of the 1930s, the root form was given as ᴹ√NAY “lament” with a dental nasal rather than a velar (Ety/NAY). Its derivatives had more to do with sadness, such as ᴹQ. naire “lament, sorrow” and N. noer “sad, lamentable”. However, it had what appeared to be an extended form ᴹ√NAYAK “pain” retaining some of its meanings from the 1910s, such as ᴹQ. naike “sharp pain”, though Tolkien did suggested this root might instead be an elaboration ᴹ√NAYKA of the root ᴹ√NAK “bite” (Ety/NÁYAK).
The root reappeared in Definitive Linguistic Notes (DLN) written around 1959 as √NAY “cause bitter grief or pain” with derivatives like Q. naica “bitterly painful or grievous” and Q. naira/S. naer “dreadful, horrible, unendurable” (PE17/151). In this same note Tolkien said √NAY influenced the meaning of √(N)DAY “dreadful, abominable, detestable” in Sindarin; see the entry on √DAY for further details.
