Look to stress local influence (4,8)
I believe the answer is:
peer pressure
'local influence' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'look to stress' is the wordplay.
'look' becomes 'peer' (to peer at something is to look at it).
'to stress' becomes 'pressure' (I've seen this in another clue).
'peer'+'pressure'='PEER PRESSURE'
Can you help me to learn more?
(Other definitions for peer pressure that I've seen before include "The influence of the Lords" , "Influence from others in one's group" , "that whips people into line?" , "Compulsion to conform to one's contemporaries" , "Influence of one's contemporaries" .)
