Sanskrit verbs and fakeverbs can show the doer, show the object, or show nothing.
When the meaning of a root is transitive you can often choose if you want it to show the doer or to show the object.
As for instance, to say irrealis things like "if we were in China we would speak Chinese", then after whatever root meaning "speak" you choose, you can add after it a tense like /liG (which may either show the doer or show the object), or you can use a /kRtya affix (which always shows the object).
When the meaning of a root is objectless you can often choose if you want it to show the doer or to show nothing.
