Blazing row in gang (7)
I believe the answer is:
roaring
'blazing' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'row in gang' is the wordplay.
'row' becomes 'oar' (oar can mean to row with oars).
'in' is an insertion indicator.
'gang' becomes 'ring' (synonyms).
'oar' placed into 'ring' is 'ROARING'.
Can you help me to learn more?
(Other definitions for roaring that I've seen before include "The Lion's part, nothing but this (MND)" , "Making cry (like a lion)" , "Sounding as a lion" , "& 1 Across Strong winds in S. Hemisphere" , "Do a - trade, - forties" .)
