Hammered -- as one's walls may be? (9)
I believe the answer is:
plastered
'hammered' is the definition.
The definition and answer can be both to do with contact as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'one's walls may be?' is the wordplay.
I cannot really understand how this works, but
'one's' could be 'as' (a thing is one thing) and 'as' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'as' is the link.
Can you help me to learn more?
(Other definitions for plastered that I've seen before include "incapable" , "Rendered" , "spread" , "Smashed" , "Pickled" .)
