So, if I understand correctly, the grammatically correct sentence is {paq vIlaDtaHvIS, pIj jIHagh}. Right ?

Because I was wondering which of these two sentences was right, and which was wrong. Although as I understand, placing the {pIj} right before the {paq vIlaDtaHvIS}, isn't actually wrong, but rather something which would occur more often while speaking as opposed to writing.

If I understand correctly your reply, in order to be grammatically correct, the adverb has to be placed right before the verb to which it refers (in our examples the {jIHagh}).

Are these conclusions correct ?

Formally, a dependent clause should not split an adverbial from its sentence, so far as we can tell.

If you did it anyway I don't think anyone would care.

And adverbials are said to come at the front of a sentence, not in front of a verb's object, so who knows? Maybe paq vIlaDtaHvIS jIHagh is the sentence, and you can put an adverbial in front of THAT.

Focus on that, rather than on what's "right" and "wrong." It's not down to right and wrong.
