Chuck half of this paddle (5)
I believe the answer is:
throw
'chuck' is the definition.
(I know that chuck is a more specific form of the action throw)
'half of this paddle' is the wordplay.
'half of' means to take half the letters.
'paddle' becomes 'row' (I've seen this in another clue).
'this' halved is 'th'.
'th'+'row'='THROW'
(Other definitions for throw that I've seen before include "Discard" , "Make a pot" , "puzzle" , "Cast, hurl" , "Try to lose" .)
