Punch is tucked inside newspaper (4)
I believe the answer is:
fist
'punch' is the definition.
'is tucked inside newspaper' is the wordplay.
I cannot really see how this works, but
'is' is present in the answer.
'newspaper' could be 'ft' (Financial Times newspaper) and 'ft' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for fist that I've seen before include "Balled hand" , "Hand with the fingers clenched in the palm" , "duke" , "Hit with a clenched one" , "Punch dispenser" .)
