On drinking limit, cardinal plastered (8)
I believe the answer is:
rendered
'plastered' is the definition.
(I've seen this before)
'on drinking limit cardinal' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'drinking limit' becomes 'nde' (I am not sure about this - if you are sure you should believe this answer much more).
'cardinal' becomes 'red' (I've seen this in other clues).
're'+'nde'+'red'='RENDERED'
Can you help me to learn more?
(Other definitions for rendered that I've seen before include "Performed - given back" , "Delivered - covered with plaster" , "Plastered; gave" , "what the builder did" , "Given; plastered" .)
