Charge with an offence (6)
I believe the answer is:
accuse
'charge with an offence' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for accuse that I've seen before include "Lay blame for wrongdoing on named person" , "Charge with a crime" , "From what Zola wrote" , "Lay blame or allege guilt" , "Arraign or indict" .)
