Why does Zle come first?
It may not be the most common word order, but it saves us from finishing the sentence with an adverb, which rarely feels natural.
wychowała Źle swoje dzieci. Is this meant to be correct?
In "Źle ona wychowała jej dzieci." I know that the "ona" is superfluous, but it's actually not allowed?
Yeah, putting it there sounds too strange.
I feel like all correct word orders should be accepted
Any particular suggestion?
What's wrong with Ona wychowala zle swoje dzieci
The adverb "źle" should rather be directly before what it refers to, which is "wychowała".
