not- vb. "reckon" (NOT); compare onot-. Passive participle nótina "counted, reckoned" (FS), nótima "countable" (PE17:68), #notië "counting, reckoning" in maquanotië "decimal system" (VT47:10), variant #nótië in caistanótië of similar meaning (VT48:11).
Quenya
caistanótië
noun. decimal system
caista
one tenth
not-
verb. reckon
nótië
counting
#nótië "counting", isolated from caistanótië, q.v.
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
maquanotië
noun. decimal system, decimal system, (lit.) *hand-counting
Notes from the late 1960s had two different words for the decimal system, maquanotie (VT47/10) and kaistanótie (VT48/11), both ending in notië “couting”, and beginning with either maqua “hand (full)” and caista “one tenth”. Of the two, I prefer maquanotie since I prefer quëan “ten” (VT48/6).
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. lempea “decimal” based on ᴱQ. lempe “ten” (QL/52).
Neo-Quenya: Since I use maquanotie for “decimal system”, I would use ᴺQ. maquëa “decimal” for purposes of Neo-Quenya as the adjective form of maqua.
quaista
one tenth
*quaista, reconstructed/updated fraction "one tenth"; see caista.
quaista
fraction. 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".
