ᴺQ. [ᴱQ.] quir- v. “to stir, make spin” (Category: to Spin)
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.
