Wander off, but get back into game plan (8)
I believe the answer is:
strategy
'game plan' is the definition.
(I've seen this in another clue)
'wander off but get back' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'get' is 'teg' which is located in the answer.
'wander' could be 'stray' (synonyms) and 'stray' is found within the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'into' acts as a link.
Can you help me to learn more?
(Other definitions for strategy that I've seen before include "Get satyr to formulate tactics" , "Systematic plan of action" , "manoeuvres" , "Plan or policy as for conducting campaign" , "Grand design" .)
