Ill-will in African country over college attended by European (6)
I believe the answer is:
malice
'ill-will' is the definition.
(I've seen this before)
'african country over college attended by european' is the wordplay.
'african country' becomes 'mali' (Mali is an example).
'over' is a charade indicator (letters next to each other).
'college' becomes 'c'.
'attended by' says to put letters next to each other.
'european' becomes 'e' (abbreviation e.g. EU).
'mali'+'c'+'e'='MALICE'
'in' is the link.
(Other definitions for malice that I've seen before include "Spite or spleen, perhaps aforethought" , "evil intent" , "Hate" , "Malevolence, spite" , "Spite, venom" .)
