Like a rebel, Andy Nicholson initially has his go in Arctic ... (11)
I believe the answer is:
anarchistic
'like a rebel' is the definition.
I can't judge whether this definition defines the answer.
'andy nicholson initially has his go in arctic' is the wordplay.
'initially' says to take the initial letters.
'has' is a charade indicator (letters next to each other).
'go in' means one lot of letters goes inside another.
The first letters of 'andy nicholson' is 'an'.
'his' inserted within 'arctic' is 'archistic'.
'an'+'archistic'='ANARCHISTIC'
Can you help me to learn more?
(Other definitions for anarchistic that I've seen before include "As unruly type" , "lacking law and order" , "Like one wanting to overthrow government" , "Revolutionary" , "Anti-government" .)
