nelquë Reconstructed

cardinal. *thirteen

One of a set of Quenya “teen” numbers appearing in rough notes on numbers from the late 1960s appearing as nelekwe likely meaning “thirteen” (VT48/21). I am of the opinion that this is a primitive form and the modern Quenya form would be ✱nelquë as suggested by Helge Fauskanger (QQ/nelequë), as further evidenced by nelquëa “✱thirteenth” from the same page. There was also a variant form quainel.

Conceptual Development: The Early Qenya Grammar of the 1910s had ᴱQ. nelkea “thirteen” based on the earlier adjectival word ᴱQ. kea “ten” (PE14/49, 82).
