Deviating, not straight (8)
I believe the answer is:
indirect
I believe this clue is a double definition.
'deviating' is the first definition.
(thesaurus)
'not straight' is the second definition.
(I've seen this before)
(Other definitions for indirect that I've seen before include "Circumlocutory" , "In credit (anag.)" , "sort of speech" , "long drawn-out" , "(Of tax) levied on goods rather than income" .)
