Risk for one willing to back directors (5,4)
I believe the answer is:
board game
'risk' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'one willing to back directors' is the wordplay.
'one willing' becomes 'game' (game can mean willing to do something).
'to back' means one lot of letters go next to another (some letters go at the back of others).
'directors' becomes 'board' (board of directors).
'game' put after 'board' is 'BOARD GAME'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for board game that I've seen before include "draughts?" , "Eg, chess, go. ludo" , "Monopoly possibly" , "Go for one" .)
