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' indicates taking the first letters.
'has' says to put letters next to each other.
'go in' is an insertion indicator.
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" .)
