to call informally
If you have questions about the conjugation of cii or Esperanto in general, you can practice and get feedback from a professional tutor.
Mi ne volas cii vin, sinjoro Esperanto, sed vi petis min.
I don't want to call you informally, Mister Esperanto, but you asked me.
Mi tute ne ciis lin!
I was totally not calling him informally!
