But {Sov} and {SIv} don't work the same way. It is stated that {SIv} can be used after {'e'} and then explicitly can be translated as "to wonder if". The semantics of the verb allow this reading.

Not so with {Sov}. Here you'd have a question as the object, which isn't allowed in Klingon.

I don't accept this translation.

That sentence can only mean:

"I don't know that Mike stole my pie."

(or perhaps in a more usual context "I didn't know that...")

Think of {SIv} as "I want to know the truth value of the sentence..." which is essentially what "wonder if" means. {Sov} doesn't seem to have that particular reading.
