Spooner's secret vessel that contains disinfectant for Cambridge, say (5-3)
I believe the answer is:
sheep-dip
This clue might be a double definition.
'spooner's' is the first definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I don't see?
'secret vessel that contains disinfectant for cambridge say' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for sheep-dip that I've seen before include "Pesticide bath for proverbially silly animals" , "'Pesticide mixture for ovines (5,3)'" , "Farm animal's bath" , "Fleece disinfectant" , "Fleece cleaner" .)
