Individual to confess (3)
I believe the answer is:
own
I believe this clue is a double definition.
'individual' is the first definition.
'confess' is the second definition.
(thesaurus)
'to' acts as a link.
(Other definitions for own that I've seen before include "Acknowledge" , "Personal; possess" , "Have in one's possession" , "Be in legal possession of (3)" , "Control" .)
