Punch correctly (5)
I believe the answer is:
right
I believe this clue is a double definition.
'punch' is the first definition.
(I've seen this before)
'correctly' is the second definition.
('right' can be a synonym of 'correctly')
(Other definitions for right that I've seen before include "Legal entitlement" , "''The customer is always .....''" , "Just - correct - title" , "Sound" , "Due" .)
