Feat of daring (5)
I believe the answer is:
stunt
'feat of daring' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stunt that I've seen before include "Check the growth of (something)" , "Limit the growth of" , "Dwarf" , "Hamper - exploit" , "Difficult (usually dangerous) feat" .)
