Back from morris dances, lubricated and the worse for wear (4-6)
I believe the answer is:
shop-soiled
'the worse for wear' is the definition.
(shop-soiled means damaged)
'back from morris dances lubricated' is the wordplay.
'back from' suggests the final letters (the letter at the back of the word).
'dances' becomes 'hops' (hop is a kind of dance).
'lubricated' becomes 'oiled' ('oil' can be a synonym of 'lubricate').
The final letter of 'morris' is 's'.
's'+'hops'+'oiled'='SHOP-SOILED'
'and' acts as a link.
(Other definitions for shop-soiled that I've seen before include "Tarnished from being on display" , "Imperfect" .)
