A noun for “bark” in the Gnomish Lexicon of the 1910s (GL/63), apparently based on the early root ᴱ√PARA [PAÐA?] which might mean “peel” (QL/72).
A verb appearing as G. gwadh- “dwell” in the Gnomish Lexicon of the 1910s with a (deleted) primitive form gu̯ađ (GL/46), likely an allusion to the early root ᴱ√ẆAÐA from the contemporaneous Qenya Lexicon (QL/102). In that document, Tolkien gave the Gnomish form as {gwath- >>} gwar-, however, which might align with the deleted primitive form ᴱ✶gu̯ara- “dwell” from the Gnomish Lexicon (GL/38).
