A verb appearing as ᴱQ. qiri- or qirna- in the Qenya Lexicon of the 1910s glossed “stir (make spin)” under the early root ᴱ√QIŘI [QIÐI] (QL/77).
Neo-Quenya: A similar root √KWER “revolve” appeared in Tolkien’s later writings (PE17/65), so I think a Neo-Root ᴺ√KWIR “stir, spin” might be used as a variant of that root. I would use ᴺQ. quir- “to stir, make spin” as its Quenya verb form.
A noun for “womanliness, femininity” in the Qenya Lexicon of the 1910s with variant qinne, both derived from the root ᴱ√QIMI (QL/31). In the entry, this word was predeceded by the definite article in parenthesis (i) and Tolkien gave it the alternate gloss “(concr.) women as a whole”; by this I assume Tolkien mean qinde by itself meant “femininity”, but with the definite article i qinde meant “women as a whole”.
