Lack a young woman (4)
I believe the answer is:
Here is my best explanation:
I believe this is a double definition.
'lack' is the first definition.
('miss' can be a synonym of 'lack')
'a young woman' is the second definition.
('miss' can be a synonym of 'young woman')
(Other definitions for miss that I've seen before include "Agatha Christie's detective", "Yearn for", "Strike noisily; criticise", "Fail to attend (event)", "Fail to see or hit", "Fail to hit (the target)", "Lass", "someone who isn't married", "Fail to hit (something)" and "maiden".)
