A word appearing as ᴱQ. lat (latt-) “flap, small hinged door, lid” in the Qenya Lexicon of the 1910s, which Tolkien considered deriving from the early root ᴱ√LAPA “enfold” (QL/51).
Neo-Quenya: For purposes of Neo-Quenya, I think this word can be salvaged as ᴺQ. lat (latt-) derived from the later root √LAT “open”, perhaps from primitive lattă with an original sense “opening”.
