Seize, nab (5)
I believe the answer is:
catch
I believe this clue is a double definition.
'seize' is the first definition.
(I know that seize is a more specific form of the action hook)
'nab' is the second definition.
(I've seen this in another clue)
(Other definitions for catch that I've seen before include "Getting round" , "Stop the motion, of a ball say" , "Intercept and hold" , "a sort of 22" , "Grab in mid-air" .)
