Blossom for a girl (3)
I believe the answer is:
may
I believe this is a double definition.
'blossom' is the first definition.
(I've seen this before)
'girl' is the second definition.
'for a' acts as a link.
(Other definitions for may that I've seen before include "The merry merry month( 3)" , "Spring" , "plant that's tropical making comeback" , "Has permission" , "Fifth month" .)
