[**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".
