Fire out of control around North? No, a conflagration (7)
I believe the answer is:
inferno
'a conflagration' is the definition.
('inferno' can be a synonym of 'conflagration')
'fire out of control around north? no' is the wordplay.
'out of control' is an anagram indicator.
'around' means one lot of letters goes inside another.
'north?' becomes 'n' ('N' can be a synonym of 'north').
'fire' anagrammed gives 'ifer'.
'ifer' enclosing 'n' is 'infer'.
'infer'+'no'='INFERNO'
(Other definitions for inferno that I've seen before include "Terrible fire" , "Large uncontrolled fire" , "hot spot" , "Dante's Hell" , "Hellish poem" .)
