Worries shown by European in distant society (5)
I believe the answer is:
fears
'worries' is the definition.
(fearing is a kind of worrying)
'european in distant society' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'in' indicates putting letters inside.
'distant' becomes 'far' (similar in meaning).
'society' becomes 's' (common abbreviation in names of organisations).
'e' going inside 'far' is 'fear'.
'fear'+'s'='FEARS'
'shown by' is the link.
(Other definitions for fears that I've seen before include "Apprehensions" , "Concerns, dreads" , "Is afraid of" .)
