Some from Baghdad ultimately grown-up (5)
I believe the answer is:
adult
'grown-up' is the definition.
(informal term for an adult)
'some from baghdad ultimately' is the wordplay.
'some from' says the answer is hidden in the clue.
'ADULT' can be found hidden inside 'baghdad ultimately'.
(Other definitions for adult that I've seen before include "One no longer young" , "No child" , "Blue" , "Mature, fully grown" , "not fit for children to see" .)
