Wilson with an unruly relation (3-2-3)
I believe the answer is:
son-in-law
'relation' is the definition.
(son-in-law is a kind of relation)
'wilson with an unruly' is the subsidiary indication.
'with' says to put letters next to each other.
'unruly' indicates an anagram.
'wilson' after 'an' is 'anwilson'.
'anwilson' with letters rearranged gives 'soninlaw'.
(Other definitions for son-in-law that I've seen before include "Relative by marriage" , "Daughter's husband" , "Member of extended family" , "He's married to your daughter" .)
