Paper in stand is European (8)
I believe the answer is:
treatise
'paper' is the definition.
(thesaurus)
'stand is european' is the wordplay.
'stand' becomes 'treat' (both can mean to provide with food).
'european' becomes 'e' (abbreviation e.g. EU).
'treat'+'is'+'e'='TREATISE'
'in' is the link.
(Other definitions for treatise that I've seen before include "Tract, monograph" , "Written study" , "Learned work on particular subject" , "Formal piece of writing on a particular subject" , "A written work about treaties" .)
