Friend's call making further play impossible (4)
I believe the answer is:
mate
'friend's' is the definition.
(I know that mate is a type of friend)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for mate that I've seen before include "First officer" , "Companion, wife" , "China" , "Match" , "Final move in chess" .)
