Curtain holder
I believe the answer is:
rod
'curtain holder' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rod that I've seen before include "Wand - fishing stick" , "The fly fisherman's stick" , "Straight, slender stick" , "axle" , "Old saying 'Spare the . . . and spoil the child'" .)
