Question regarding nominatives: magister and magistra
(I) Regarding the genitive singular (masculine) word: <<magistri>>
Question: Is the genitive plural (masculine) spelled as <<magistrorum>> correct?
(II) Regarding the genitive singular (feminine) word: <<magistrae>>
Question: Is the genitive plural (feminine) spelled as <<magistrarum>> correct?
I think I am ninety-nine percent sure for both. I hope it's not magistorum and magistarum.
