Get back into abandoned policy (8)
I believe the answer is:
strategy
'policy' is the definition.
(thesaurus)
'get back into abandoned' is the wordplay.
'back' says the letters should be written backwards.
'into' means one lot of letters goes inside another.
'abandoned' becomes 'stray' (I am not sure about this - if you are sure you should believe this answer much more).
'get' backwards is 'teg'.
'teg' going into 'stray' is 'STRATEGY'.
Can you help me to learn more?
(Other definitions for strategy that I've seen before include "Get satyr to formulate tactics" , "Planning and direction of campaign" , "Grand design" , "Plan for achieving a particular long-term aim" , "Overall plan for campaign" .)
