... stops to embrace single second lady (8)
I believe the answer is:
baroness
'lady' is the definition.
(I've seen this before)
'stops to embrace single second' is the wordplay.
'stops' becomes 'bars'.
'to embrace' is an insertion indicator.
'single' becomes 'one' (I've seen this before).
'second' becomes 's' (common abbreviation).
'bars' enclosing 'one' is 'barones'.
'barones'+'s'='BARONESS'
(Other definitions for baroness that I've seen before include "Noble" , "Lady peer" , "Aristocrat" , "Woman life-peer" , "Noblewoman" .)
