A word appearing as ᴱQ. lapil “a swathe, a flowing cloth” in the Qenya Lexicon of the 1910s under the early root ᴱ√LAPA “enfold” (QL/51).

Neo-Quenya: The root √LAP “fold, bend” reappears in Tolkien’s later writings, so I’d retain ᴺQ. lapil “swathe, flowing cloth” for purposes of Neo-Quenya, used of both a broad area of some covering or crop (“swathe”) as well as a large piece of loose cloth.
