One of a set of Quenya “teen” numbers appearing in rough notes on numbers from the late 1960s, likely meaning “fifteen” (VT48/21). It had a variant quailepen later in the same page.
Conceptual Development: The Early Qenya Grammar of the 1910s had ᴱQ. lenkea or leminkea “fifteen” based on the earlier adjectival word ᴱQ. kea “ten” (PE14/49, 82).
quailepen, cardinal "fifteen" (but lepenquë may be preferred) (VT48:21)
