the word 'accomplice' if used in a sentence, would it be accompanied with the word 'to' or 'in'.........."accomplice to" or accomplice in"
In American English, either would be correct. One can be an accomplice to a crime or in a crime. My personal usage is to use "to" before a general crime or situation and "in" in other uses.
I would use:
He was an accomplice to murder.
He was an accomplice in the murder of Tom Jones.
He was an accomplice in the commission of that bank robbery.
I should add, however, that this might just be my personal preference.
