Enthusiastic European person (strong) that is not heartless (9)
I believe the answer is:
ebullient
'enthusiastic' is the definition.
(I've seen this before)
'european person strong that is not heartless' is the wordplay.
I cannot really see how this works, but
'european' could be 'e' (abbreviation e.g. EU) and 'e' is found in the answer.
'person' could be 'bull' (bull is a kind of person) and 'bull' is found within the answer.
'not' could be 'nt' (synonyms) and 'nt' is found in the answer.
'that is' could be 'ie' (short for Latin 'id est', 'that is') and 'ie' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ebullient that I've seen before include "Jolly" , "cock- a-hoop" , "Full of cheerful enthusiasm" , "Enthusiastic" , "Libel tune (anag.)" .)
