One of a set of Quenya “teen” numbers appearing in rough notes on numbers from the late 1960s appearing as tolokwe and likely meaning “eighteen” (VT48/21). I am of the opinion that this is a primitive form, and the modern Quenya form would be ✱tolquë, though ✱toloquë is certainly possible.
Conceptual Development: The Early Qenya Grammar of the 1910s had ᴱQ. tolkea “eighteen” based on the earlier adjectival word ᴱQ. kea “ten” (PE14/49, 82). Tolkien indicated this word was rare, supplanted by ᴱQ. hualqe, which might have been borrowed from duodecimal counting; see its entry for discussion.
toloquë ("kw") cardinal "eighteen" (VT48:21). If "tolokwe" is seen as a Common Eldarin form, it is possible that the Quenya word should be *tolquë instead, but the editor assumes that "tolokwe" is merely an unusual spelling of Quenya toloquë (since "tolokwe" is listed together with forms that are definitely Quenya).
