Move like a drunken churl (5)
I believe the answer is:
lurch
'move' is the definition.
(lurch is a kind of move)
'a drunken churl' is the wordplay.
'a drunken' indicates anagramming the letters.
'churl' anagrammed gives 'LURCH'.
'like' is the link.
(Other definitions for lurch that I've seen before include "Stagger; abandoned, if left in it" , "Walk with unsteady swaying movements" , "Move abruptly to one side" , "Sudden unsteady move" , "in position lacking support?" .)
