Marshal Foch, evidently, did not have everything! (4)
I believe the answer is:
half
'have everything' is the definition.
Both the answer and definition are adjectives.
Maybe you can see a link between them that I don't see?
'marshal foch evidently did not' is the wordplay.
'HALF' is hidden in amongst the letters.
But, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for half that I've seen before include "Some football" , "Short distance - steal!" , "Two of these to the pint" , "0.5" , "little drink" .)
