The knowledge and values shared by a society (7)
I believe the answer is:
culture
'the knowledge and values shared by a society' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for culture that I've seen before include "Grown preparation of cells; the arts" , "Set of ideas and values of a group" , "Growth of bacteria" , "Attitudes and values of a society" , "Grow (eg, bacteria, tissue cells) in artificial media" .)
