Press club includes hard element (4)
I believe the answer is:
iron
This clue is a quadruple definition!!
'press' is the first definition.
(I know that press can be written as iron)
'club' is the second definition.
(type of golf club)
'includes' is a link.
'hard' is the third definition.
(thesaurus)
'element' is the fourth definition.
(I know that iron is a type of metal)
(Other definitions for iron that I've seen before include "uncompromising" , "Metallic chemical element" , "Fe - golf club" , "inflexible > club" , "Metal - press" .)
