Ride? Finished circuit (7)

Ross

I believe the answer is:

overlap

'ride?' is the definition.
(thesaurus)

'finished circuit' is the wordplay.
'finished' becomes 'over' ('over' can be similar in meaning to 'finished').
'circuit' becomes 'lap' ('lap' can be a synonym of 'circuit').
'over'+'lap'='OVERLAP'

(Other definitions for overlap that I've seen before include "Partly cover (another object)" , "Extend over and cover a part of" , "Coincide in part" , "Imbricate" , "Flap" .)

I've seen this clue in The Telegraph.
