Badger in road lay down (6)
I believe the answer is:
ordain
'lay down' is the definition.
(I've seen this before)
'badger in road' is the wordplay.
'badger' indicates an anagram (the letters must be badgered or bothered).
'in'+'road'='inroad'
'inroad' with letters rearranged gives 'ORDAIN'.
(Other definitions for ordain that I've seen before include "Either prescribe" , "Decree or appoint to priesthood" , "Rule" , "frock" , "Decree and admit to holy orders" .)
