I have been noting down miscillaneous gaps in my understanding as they've appeared over the previous week.
1. The use of case in personal pronouns in the following structures is confusing me.
* А что случилось с его чрезвычайной коммиссей?
* Когда я буду в Москве, я позвоню его сестре.
* В течение этого времени я думал о моём друге Владимире.
The first two examples, where the personal pronouns are accusative (его)
They are possessive.
What happened to his special commission?
I was thinking about my friend.
