Morally correct eccentric hit Alec (7)
I believe the answer is:
ethical
'morally correct' is the definition.
(I've seen this before)
'eccentric hit alec' is the wordplay.
'eccentric' is an anagram indicator.
'hit'+'alec'='hitalec'
'hitalec' is an anagram of 'ETHICAL'.
(Other definitions for ethical that I've seen before include "Morally proper" , "Morally correct, honourable" , "Moral, principled" , "Relating to morals" , "lt's available on prescription only" .)
