Toss, chuck (5)
I believe the answer is:
throw
I believe this is a double definition.
'toss' is the first definition.
(I know that toss is a more specific form of the action the throw)
'chuck' is the second definition.
(I know that chuck is a more specific form of the action the throw)
(Other definitions for throw that I've seen before include "shot-put event?" , "Chuck - confuse" , "Discard" , "pitch or > floor" , "Organise party" .)
