Charge around on roundabout (8)
I believe the answer is:
indirect
'roundabout' is the definition.
(similar in meaning)
'charge around on' is the wordplay.
'charge' becomes 'indict' (indicting is a kind of charging).
'around' indicates putting letters inside.
'on' becomes 're' ('on' can be mean 'with reference to').
'indict' enclosing 're' is 'INDIRECT'.
(Other definitions for indirect that I've seen before include "Not going straight to the point" , "Deviating, not straight" , "In credit, not being straight" , "Circuitous, oblique" , "Roundabout, circuitous" .)
