Relative is hesitant to leave Arkansas (5)
I believe the answer is:
uncle
'relative' is the definition.
(uncle is a kind of relative)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for uncle that I've seen before include "Dad's brother" , "older relative" , "Male relation; pawnbroker" , "For example, Tom Cobbleigh" , "Brother of one's parent" .)
