Fail to get girl (4)
I believe the answer is:
miss
I believe this is a double definition.
'fail to get' is the first definition.
(I've seen this before)
'girl' is the second definition.
(term of address for an unmarried woman)
(Other definitions for miss that I've seen before include "Skip" , "Feel the absence of" , "Fail to meet - girl" , "Girl or unmarried woman" , "Musical set in Vietnam" .)
