Singer letting off steam (6)
I believe the answer is:
kettle
This could be a double definition.
'singer letting' is the first definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'steam' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'off' acts as a link.
Can you help me to learn more?
(Other definitions for kettle that I've seen before include "Container for heating 10" , "In which to boil water or cook fish" , "Vessel for boiling liquids" , "Water-boiler" , "Check elements causing trouble in demonstration" .)
