Daughter torn apart, being highly motivated? (6)
I believe the answer is:
driven
'highly motivated?' is the definition.
(I've seen this before)
'daughter torn apart' is the wordplay.
'daughter' becomes 'd'.
'torn apart' becomes 'riven' (I've seen this before).
'd'+'riven'='DRIVEN'
'being' is the link.
(Other definitions for driven that I've seen before include "Urged or forced along" , "Propelled like a hard bargain" , "Given a lift" , "Determined" , "Forced, compelled" .)
