End call for display (4,2)
I believe the answer is:
hang up
This might be a double definition.
'end' is the first definition.
(I know that break off is the is a more specific form of the action of hang up.)
'call for display' is the second definition.
'hang up' can be an answer for 'call' (I have seen 'Close call ' mean 'hang up' so perhaps 'call' could also mean 'hang up'). I am not certain of the 'for display' bit.
Can you help me to learn more?
(Other definitions for hang up that I've seen before include "Modern term for emotional inhibition - get off the phone" , "Psychologically problematic" , "end conversation abruptly?" , "An informal inhibition or emotional problem" , "Close call" .)
