Shout abandoning last two with demonstration (4)
I believe the answer is:
show
'demonstration' is the definition.
(show is a kind of demonstration)
'shout abandoning last two with' is the wordplay.
I cannot quite see how this works, but
'with' could be 'w' (short for with) and 'w' is located in the answer.
The remaining letters 'sho' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for show that I've seen before include "Screen" , "event" , "Point out - parade" , "Exhibit - present" , "Display; prove" .)
