Gnomish
cwîr
noun.cream
A noun appearing as G. cwîr “cream” in the Gnomish Lexicon of the 1910s (GL/28), clearly related to ᴱQ. qirme “cream” and thus derived from the early root ᴱ√QIŘI (QL/77).
Neo-Sindarin: I would adapt this word as ᴺS. pîr “cream” for purposes of Neo-Sindarin from a Neo-Root ᴺ√KWIR “stir”, with ancient *kw* becoming *p* as was usual in Sindarin.
