In fight notice something piercing? (7)
I believe the answer is:
bradawl
'something piercing?' is the definition.
I can't judge whether this defines the answer.
'in fight notice' is the wordplay.
'in' indicates putting letters inside.
'fight' becomes 'brawl' (brawl is a kind of fight).
'notice' becomes 'ad' (both can mean an advertisement).
'brawl' enclosing 'ad' is 'BRADAWL'.
Can you help me to learn more?
(Other definitions for bradawl that I've seen before include "it has a point" , "Piercing tool" , "Boring article" , "one that bores" , "sharp-pointed object" .)
