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' is an anagram indicator (out can mean wrong or inaccurate).
'european' becomes 'E' (abbreviation e.g. EU).
'sent' mixed up with 'e' can make '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" .)
