Absent young woman at home? Good (7)
I believe the answer is:
missing
'absent' is the definition.
('missing' can be similar in meaning to 'absent')
'young woman at home? good' is the wordplay.
'young woman' becomes 'miss' ('miss' can be a synonym of 'young woman').
'at home?' becomes 'in' ('in' can be similar in meaning to 'at home').
'good' becomes 'g' (abbreviation).
'miss'+'in'+'g'='MISSING'
(Other definitions for missing that I've seen before include "Lost without" , "Absent with location unknown" , "Not to be found" .)
