'no' is the definition.
(I've seen this before)

'it can't stop you getting nailed' is the wordplay.
'nailed' can be anagrammed to 'DENIAL'.
But, I'm unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for denial that I've seen before include "Nailed (anag.)" , "Refusal, abnegation" , "Refusal to admit painful truths" , "Repudiation" , "Renunciation" .)

I've seen this clue in the Evening Standard.
