Took up (7)
I believe the answer is:
adopted
'took up' is the definition.
('adopt' can be a synonym of 'take up')
This is the entire clue.
(Other definitions for adopted that I've seen before include "Espoused" , "Chose to follow" , "Took into one's family" , "Like issue raised by others" , "Taken as one's own" .)
