Relatives like to go around free (7)
I believe the answer is:
aunties
'relatives' is the definition.
(auntie is a kind of relative)
'like to go around free' is the wordplay.
'like' becomes 'as'.
'to go around' means one lot of letters goes inside another.
'free' becomes 'untie' (I've seen this before).
'as' placed around 'untie' is 'AUNTIES'.
(Other definitions for aunties that I've seen before include "older women" , "Females relations" , "Older female friends" , "Parent's sisters (informal)" , "some women in family" .)
