I have a doubt regarding the correct preposition usage for the word absolve.
The court has absolved him from all the charges leveled against him.
And another example,
I absolve you of all your sins.
I googled for a bit and found this answer Proper preposition for "absolve" but the confusion remained.
Could someone tell me why the two prepositions have not been used interchangeably in these sentences? And are there any markers which can help one identify the correct preposition?
