Sent out with European kids (5)
I believe the answer is:
teens
'kids' is the definition.
Although both the answer and definition are nouns, they are not in the same form of the noun.
'sent out with european' is the wordplay.
'out with' indicates anagramming the letters (out can mean wrong or inaccurate).
'european' becomes 'E' (abbreviation e.g. EU).
'sent' anagrammed with 'e' gives 'TEENS'.
Can you help me to learn more?
(Other definitions for teens that I've seen before include "Adolescence" , "Years 13-19" , "13-19 age group" , "children" , "Adolescent years" .)
