Presses school club first (5)
I believe the answer is:
irons
'presses' is the definition.
(I know this)
'school club first' is the wordplay.
'school' becomes 'S'.
'club' becomes 'iron' (type of golf club).
'first' is a charade indicator (letters next to each other).
's' after 'iron' is 'IRONS'.
(Other definitions for irons that I've seen before include "Golf-clubs with metal heads" , "Smooths the golfclubs?" , "Smooths, presses" , "Devices restricting personal freedom in prisons" , "Golf clubs with metal heads" .)
