Grapple with garment? (4)
I believe the answer is:
cope
I believe this is a double definition.
'grapple' is the first definition.
(I know that grapple can be written as cope)
'garment?' is the second definition.
(type of religious cloak)
'with' acts as a link.
(Other definitions for cope that I've seen before include "Priest's cloak; deal (with)" , "Manage, make do" , "Manage effectively" , "Deal with, manage successfully" , "top on wall" .)
