Conforming to the normal flag (8)
I believe the answer is:
standard
'flag' is the definition.
(I know that standard is a type of flag)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for standard that I've seen before include "Reference point, benchmark" , "Touchstone, benchmark 98)" , "Flag - of the usual kind" , "Jack" , "Flying colours" .)
