Plan is to get back and wander round (8)
I believe the answer is:
strategy
'plan' is the definition.
(I know that strategy is a type of plan of action)
'get back and wander round' is the wordplay.
I cannot quite see how this works, but
an anagram of 'get' is 'teg' which is within the answer.
'wander' could be 'stray' (synonyms) and 'stray' is found within the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'is to' is the link.
Can you help me to learn more?
(Other definitions for strategy that I've seen before include "Systematic plan of action" , "Plan or policy as for conducting campaign" , "Plan for achieving a particular long-term aim" , "Scheme" , "Plan or policy to achieve something" .)
