European staff (4)
I believe the answer is:
pole
I believe this clue is a double definition.
'european' is the first definition.
(someone from Poland)
'staff' is the second definition.
(both can mean a stick)
(Other definitions for pole that I've seen before include "Rod; shaft; European" , "'Round rod, of wood say (4)'" , "Staff" , "One of two opposites" , "Magnet end" .)
