Give the slip
I believe the answer is:
evade
'give the slip' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for evade that I've seen before include "Dodge, steer clear of" , "Dodge by cleverness or trickery" , "Escape paying (tax)" , "Get round" , "Dodge by cleverness (5)" .)
