Ghoulish family member in list (5)
I believe the answer is:
lurch
'list' is the definition.
(both can mean move in an unnatural way)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for lurch that I've seen before include "Stagger; abandoned, if left in it" , "Sudden unsteady move" , "Walk with unsteady swaying movements" , "Move abruptly to one side" , "Abrupt uncontrolled movement - something not to be left in?" .)
