The club was prepared to, you say (4)
I believe the answer is:
wood
'the club' is the definition.
(wood is a kind of club)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for wood that I've seen before include "Material from trees" , "Driver, perhaps" , "'Under Milk - - ' (lit.)" , "What you might need to play golf" , "Section of orchestra" .)
