Catch the sound of the waves! (5)
I believe the answer is:
seize
'catch' is the definition.
(I know that seize is a type of hook)
'sound of the waves' is the wordplay.
'sound of' shows a homophone (sound like).
'the waves' becomes 'seas' (I've seen this in another clue).
'seas' is a homophone of 'SEIZE'.
'the' is the link.
(Other definitions for seize that I've seen before include "Snatch" , "Capture" , "Grab by force" , "Grab suddenly" , "Confiscate" .)
