Support for the staff (4)
I believe the answer is:
pole
I believe this clue is a double definition.
'support' is the first definition.
(I know that pole is a kind of support)
'staff' is the second definition.
(I've seen this before)
'for the' is the link.
(Other definitions for pole that I've seen before include "may be magnetic?" , "Magnet end" , "Rod, perch" , "(or north or eouth?)" , "location where it is always very cold" .)
