Just to sum up (as all these is quite complicated for me and for learners) ; and please if possible, check my findings : 1.HIS wife (f) wants her castle. > Jeho žena chce SVŮJ hrad.. 2.HIS wife (f) wants his castle. > Jeho žena (f) chce JEHO hrad.. 3.HIS wife (f) wants my castle. > Jeho žena chce MŮJ hrad.. 4.HER husband (m) wants his castle. > Její muž chce SVŮJ hrad. 5. Her husband (m) chce her castle. JEJÍ muž chce JEJÍ hrad. I wonder what grade I would deserve here..
