Unsettled agent on centre of driving range (8)
I believe the answer is:
vagabond
'unsettled' is the definition.
(similar in meaning)
'agent on centre of driving range' is the wordplay.
'agent' becomes 'bond' (James Bond).
'on' means one lot of letters go next to another.
'centre of driving' becomes 'v' (I can't explain this - if you can you should give a lot more credence to this answer).
'range' becomes 'aga' (type of cooking range).
'v'+'aga'='vaga'
'bond' after 'vaga' is 'VAGABOND'.
Can you help me to learn more?
(Other definitions for vagabond that I've seen before include "One wandering" , "Roving" , "Beggar" , "One having no settled home" , "An idle or dishonest wanderer" .)
