Whole that's greater than the sum of its parts (7)
I believe the answer is:
gestalt
'whole that's greater than the sum of its parts' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for gestalt that I've seen before include "Pattern perceived as whole" , "whole of psychology" , "Organised whole, more than the sum of its parts" , "establish a pattern" .)
