enquë
cardinal. six
enquë ("q") cardinal "six" (ÉNEK, VT48:4, 6, 9, VT49:57); enquëa ordinal "sixth" (VT42:25); see also enquië. According to VT48:8, the word for "six" may have been encë ("k") in very early Quenya (the form is asterisked by Tolkien), but this was altered to enquë under the influence of yunquë "twelve" (perceived as meaning "2 times 6", *yú-enquë, with the prefix yú- "twi-").
yuncë
cardinal. twelve
yuncë ("k") cardinal "twelve", before it was altered to yunquë under the influence of minquë "eleven" (according to VT48:7, 8). The form yuncë is asterisked by Tolkien. Compare encë under enquë.

yunquëa

entë
moreover, further, furthermore, what is more
entë (1) conj. "moreover, further, furthermore, what is more" (VT47:15, VT48:14). Compare yunquentë as a variant of yunquenta, q.v.
nelequë
cardinal. thirteen
?nelequë ("kw") cardinal "thirteen" (VT48:21). The spelling "nelekwe" occurring in the primary source could suggest that this is really a Common Eldarin form; if so, one could theorize that the Quenya form would be *nelquë with syncope of the middle vowel (the same source lists "minikwe" as a word for 11, and the Quenya form is known to be minque). Compare nelquëa*. On the other hand, "tolokwe" as a word for 18 is listed together with definite Quenya forms and is apparently an unorthodox spelling of toloquë** (as observed by the editor); here no syncope producing *tolquë occurs. Thus toloquë could support ?nelequë as the Quenya word (but because of the uncertainties, yunquentë may be preferred as the word for 13).
nelquëa
cardinal. thirteen
nelquëa, cardinal "thirteen" (?) (VT48:21). This looks like an odd form next to other cardinals that simply end in -quë (like lepenquë, enenquë, otoquë = 15, 16, 17), and the form "nelekwe" also listed may indicate another Quenya form nelequë (q.v.) or *nelquë (but because of the uncertainties, yunquentë may be preferred as the word for 13). By another theory, nelquëa* is the ordinal "thirteenth", corresponding to the cardinal nel(e)quë**.
quainel
cardinal. thirteen
quainel, cardinal "thirteen" (but yunquentë may be preferred) (VT48:21)
rasta
cardinal. twelve
#rasta cardinal "twelve" (isolated from yurasta_ "24", two times 12; cf. the stem RÁSAT "twelve" listed in the Etymologies). See yunquë. (PE14:17)_
yurasta
cardinal. twelve
yurasta cardinal "24" (two times #rasta "twelve") (PE14:17)
yunquë ("q") cardinal "twelve" (VT47:41, VT48:4, 6, 9; VT49:57; also compare the stem yunuk(w)-_ cited in VT42:24, 31). This word appears already in an early source (PE14:82)_. Some sources point to #rasta, q.v., as another word for "twelve". However, available post-LotR sources indicate that Tolkien intended yunquë as the regular Quenya word for "twelve".
