Lay claim to right (11)
I believe the answer is:
appropriate
I believe this is a double definition.
'lay claim to' is the first definition.
(to lay claim to something is to appropriate it)
'right' is the second definition.
(similar in meaning)
(Other definitions for appropriate that I've seen before include "Proper; take" , "half-inch" , "Trouser" , "Whip" , "Fit" .)
