Father is from Spain? Correct! (6)
I believe the answer is:
revise
'correct' is the definition.
(thesaurus)
'father is from spain?' is the wordplay.
'father' becomes 'rev' (I've seen this in other clues**).
'from' is a charade indicator (letters next to each other).
'spain?' becomes 'e' (abbreviation for Espana).
'rev'+'is'+'e'='REVISE'
(Other definitions for revise that I've seen before include "Go over study material again" , "Improve, amend" , "Change - cram" , "Go over books and notes again to refresh memory" , "proof" .)
