I'm in European country for evaluation (8)
I believe the answer is:
estimate
'for evaluation' is the definition.
(thesaurus)
'i'm in european country' is the wordplay.
'in' indicates putting letters inside.
'european' becomes 'e' (abbreviation e.g. EU).
'country' becomes 'state' (synonyms).
'e'+'state'='estate'
'im' put within 'estate' is 'ESTIMATE'.
(Other definitions for estimate that I've seen before include "Make an educated guess" , "Judgement of approximate value or size" , "Meatiest (anag) - figure" , "Tease Tim (anag.)" , "Calculate in approximate way" .)
