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**.

?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).
