Roundabout working in credit (8)
I believe the answer is:
indirect
'roundabout' is the definition.
(similar in meaning)
'working in credit' is the wordplay.
'working' indicates anagramming the letters.
'in'+'credit'='incredit'
'incredit' anagrammed gives 'INDIRECT'.
(Other definitions for indirect that I've seen before include "Circumlocutory" , "Roundabout (route)" , "(Of tax) levied on goods rather than income" , "Not going straight to the point" , "Not following the shortest way" .)
