I have a question regarding the use of the verb "to convict" with preposition "on".
We can use this verb with the preposition "of" plus a noun or gerund.
He was convicted of stabbing a stranger in a bar brawl.
He was convicted of involuntary manslaughter.
You can look it up in almost every major online dictionary (Cambridge, Oxford, etc), however, this verb is also used with the preposition "on" but the problem is that none of those English online dictionaries mention it.
- He was convicted on fraud charges.
- She was convicted on trumped up charges.
If it is grammatically correct and acceptable to use this preposition with this verb, why do not they add it on their websites? Maybe it is due to AmE/BrE differences?
