An adjective appearing as G. {cwild >>} cwîl “quiet, peaceful, gentle” in the Gnomish Lexicon of the 1910s (GL/28). It is clearly related to ᴱQ. qilda “quiet, hushed, still” based on the early root ᴱ√QḶŘḶ [QḶÐḶ] (QL/78).
Neo-Sindarin: For purposes of Neo-Sindarin I would adapt this word as ᴺS. pell fitting the Sindarin phonetic developments from primitive ✱kwildā as originally suggested by Fiona Jallings, but Fiona gave it the same gloss as its Early Qenya equivalent, whereas I would use the glosses “quiet, peaceful, gentle” from Gnomish.
A noun in the Gnomish Lexicon of the 1910s for “a leg” (GL/21), clearly with a different etymology than ᴱQ. pelko “leg” (QL/73), probably derived instead from the early root ᴱ√VAHA “travel” (QL/99).
