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).
