Joy Orwell originally found in European language (7)
I believe the answer is:
elation
'joy' is the definition.
(elation is a kind of joy)
'orwell originally found in european language' is the wordplay.
'originally' indicates taking the first letters.
'found in' means one lot of letters goes inside another.
'european' becomes 'e' (abbreviation e.g. EU).
'language' becomes 'latin' (Latin is an example**).
The first letter of 'orwell' is 'o'.
'e'+'latin'='elatin'
'o' inserted within 'elatin' is 'ELATION'.
(Other definitions for elation that I've seen before include "High feeling?" , "Transport" , "It's a great feeling!" , "Exaltation" , "Feeling of delight, joy" .)
