Broken tie with adult brings freedom (8)
I believe the answer is:
latitude
'freedom' is the definition.
(I know that latitude is a type of freedom)
'broken tie with adult' is the wordplay.
'broken' indicates anagramming the letters.
'with' is a charade indicator (letters next to each other).
'tie' after 'adult' is 'adulttie'.
'adulttie' is an anagram of 'LATITUDE'.
'brings' acts as a link.
(Other definitions for latitude that I've seen before include "'Leeway, scope (8)'" , "Unrestricted" , "Poles' approach increases such" , "seen the world over" , "Imaginery line around the earth" .)
