A noun in the Gnomish Lexicon of the 1910s meaning “flight, power of flight”, clearly based on ᴱ✶du̯il from which G. duiling “swallow” [bird] was derived (GL/31). The word duil also functioned as an adjective meaning “having power of flight, fledged”, but there was a more proper adjective form G. duileg with these meanings as well.
