Make a concerted effort to win a lady (3-8)
I believe the answer is:
get-together
'make' is the definition.
(I know that make is a more specific form of the action get together)
'a concerted effort to win a lady' is the wordplay.
'a concerted effort' becomes 'get' (I can't explain this - if you can you should believe this answer much more).
'win' becomes 'get'.
'a lady' becomes 'her' (her refers to a woman).
'get'+'to'+'get'+'her'='GET-TOGETHER'
Can you help me to learn more?
(Other definitions for get-together that I've seen before include "Assemble" , "An informal party" , "Informal meeting" , "informal social gathering" .)
