-n (2), also -nyë, pronominal ending, 1st person sg. "I" (VT49:51), as in utúlien "I am come" (EO), cainen "I lay" (VT48:12-13), carin or carinyë "I do" (VT49:16), veryanen *"I married" (VT49:45). See also VT49:48. Long form -nye- with object ending -s "it" following in utúvienyes (see tuv-). A possible attestation of -n in object position ("me") is provided by the untranslated verbal form tankassen (PE17:76), where -n may be preceded by -sse- as a longer form of the 3rd person sg. ending -s (see -s #1).

caista
one tenth
[caista] ("k"), fraction "one tenth" (1/10), also cast, an unusual Quenya form since the language does not normally tolerate two consonants finally (VT48:11). Compound caistanótië ("k") "decimal system" (in counting) (ibid.) However, Tolkien later rejected the root KAYAN "ten" in favour of KWAYA(M), changing the cardinal "ten" from cainen to quain, quëan (VT48:13). Apparently we must therefore read *quaista as the new fraction "one tenth".
quain
cardinal. ten
quain cardinal "ten" (also quëan); quainëa ordinal "tenth" (VT48:6, 20; VT42:25). Quain or quëan replaced the form cainen in Tolkiens conception.
quëan
cardinal. ten
quëan cardinal "ten", also quain (VT48:6, 12, 20). Quain or quëan replaced the form cainen in Tolkiens conception.
quëan
cardinal. ten
Eldarinwe Leperi are Notessi (ELN) from 1968 had the words quëan and quain for “ten” (VT48/6). The latter was used in adjectival quainëa “tenth” (VT42/25), and on this basis I believe quain is the form used in compounds, while quëan is its form as an independent word. Its primitive form is ✶kwayam based on the root √kwaya originally referring to the whole (√KWA) set of ten fingers (VT42/24).
Conceptual Development: Tolkien introduced this word for “ten” fairly late in his life. In the Qenya Lexicon of the 1910s the word for “ten” was ᴱQ. lempe, related to ᴱQ. lemin “five” and appearing under the early root ᴱ√LEH [LEǶE] (QL/52). In the Early Qenya Grammar (EQG) of the 1920s, the base word for “ten” was ᴱQ. kai, already referring to the ten fingers (PE14/51, 84). In combination with other numbers it used its partitive form ᴱQ. kainen “ten” as in ᴱQ. yukainen “twenty” = “✱two of ten”, ᴱQ. otsokainen “seventy” = “✱seven of ten”, and so forth (PE14/49, 82-83). It had an adjectival variant ᴱQ. kea also used in the “teen” numbers: ᴱQ. kankea “fourteen” (PE14/49, 82).
In The Etymologies of the 1930s the partitive form became the normal form ᴹQ. kainen “ten” under root ᴹ√KAYAN of the same meaning (Ety/KAYAN). The form cainen “ten” continued to appear in Tolkien’s later writings (PE17/95; CPT/1296) along with a shorter form cëa. This short form kea(n) appeared in rough notes associated with ELN from 1968, replacing kainen to avoid confusion with cainen “I lay”. Ultimately in this document Tolkien settled on quëan/quain as mentioned above.
Neo-Quenya: For purposes of Neo-Quenya, I use quëan “ten” as an independent word and quain in compounds such as ᴺQ. yuquain “twenty” = “two tens”.
cëa(n)
cardinal. ten
caista
fraction. one tenth
A word appearing as kaista or kast “1/10” in notes on numbers from the late 1960s, a combination of √KAYAN “ten” with the fractional suffix -sta.
Neo-Quenya: Since I prefer quëan for “ten”, I would use ᴺQ. quaista “one tenth” for purposes of Neo-Quenya as suggested by Helge Fauskanger (QQ/quaista).
Conceptual Development: The Early Qenya Grammar of the 1920s had ᴱQ. keatto or kesto “one tenth” with adjective forms ᴱQ. keatya or kestya (PE14/51, 84). All of these words were related to 1920s ᴱQ. kea “ten”.
cast
one tenth
[cast] ("k"), fraction "one tenth", but the form is apparently obsolete; see caista. (VT48:11)
cast
fraction. one tenth
cëa
cardinal. ten
[cëa, cëan ("k") cardinal "ten", forms Tolkien later abandoned in favour of quain or quëan. An adjectival form caina ("k") was also listed, but must likewise be considered obsolete. (VT48:12-13, VT49:54)]
quain
cardinal. ten
quaista
one tenth
*quaista, reconstructed/updated fraction "one tenth"; see caista.
quaista
fraction. one tenth
[cainen] ("k") cardinal "ten" (KAYAN/KAYAR). According to VT48:12, Tolkien eventually rejected this word (cainen would only mean "I lay", sc. the pa.t. cainë with the ending -n "I"). See quain, quëan.
