Consider the following sentences:
Get thee hence, lest we too die on your account!
Get thee hence, lest we too die on account of you!
My intuition is that the two are identical in meaning, the former merely sounding more melodious. However, since I know others who disagree, I am looking for a vaguely authoritative source (preferable descriptive, rather than prescriptive; i.e. giving examples of usage to prove its point).
The argument I have heard is that 'on your account' is equivalent to 'for your benefit', and cannot mean 'because of you', unlike 'on account of you', which can. This seems to be corroborated by Google's dictionary, but not by the Cambridge English Dictionary.
An ideal answer would cite a discussion of this particular topic, or provide real usage examples (from reputable sources).
