The point of the question is that I want "of mine" to indicate "inattention".
Where should "of mine" be in the sentence below? This is the fault of the inattention of mine.
This is the inattention's fault.
If I add "of mine" at the end of the sentence, then, Do I indicate "the fault" not "inattention" or what?
This is the inattention's fault of mine.
