querma

noun. spinning wheel, turn-table, spinning wheel, turn-table, *wheel

A noun for “a spinning wheel or turn-table” in notes from around 1965, derived from √KWER “revolve” (PE17/65).

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. qirin “a wheel” under the early root ᴱ√QIŘI [QIÐI] having to do with stirring and spinning (QL/77).

Neo-Quenya: For purposes of Neo-Quenya, I would also use querma for an ordinary “wheel” such as on carts.

Gnomish

cwiruin

noun. spinning wheel

A word appearing as G. {cwirmin >>} cwiruin “spinning wheel” in the Gnomish Lexicon, an elaboration of G. cwir- “make spin” though the function of the suffix -uin is unclear (GL/28).

Neo-Sindarin: Since I update the Gnomish verb to ᴺS. pir- “make spin”, I would likewise update this noun to ᴺS. piruin “spinning wheel”.
