Name among European set, foremost of socialists (6)
I believe the answer is:
engels
'name among european set foremost of socialists' is the definition.
I can't tell whether this defines the answer.
'name among european set foremost of socialists' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'among' is an insertion indicator.
'european' becomes 'e' (abbreviation e.g. EU).
'set' becomes 'gel' (I've seen this before**).
'foremost of' indicates taking the first letters.
The initial letter of 'socialists' is 's'.
'e'+'gel'='egel'
'n' placed within 'egel' is 'engel'.
'engel'+'s'='ENGELS'
Can you help me to learn more?
