Long for girl (4)
I believe the answer is:
miss
I believe this is a double definition.
'long for' is the first definition.
(thesaurus)
'girl' is the second definition.
('miss' can be a synonym of 'girl')
(Other definitions for miss that I've seen before include "Agatha Christie's detective" , "Lass" , "Fail to hit (something)" , "someone who isn't married" , "Fail to attend (event)" .)
