Is this sentence wrong? Must an action verb like 買いました always use を？


父は姉のセーター **が** デパートで買いました。

Is this sentence wrong due to the が? Must an action verb like 買いました always use
を？

I don't remember where I read it, but it said that in many cases, using が will
not be wrong since it marks a statement. While if the verb require が (such as
すき or 欲しい）it will be wrong to use を.




Yes, it is. セーター in your example sentence is a object, so you must use を
because を is usually used for a object.

As for すき and 欲しい, you are right.
