Murphy’s coat? (6)
I believe the answer is:
jacket
This could be a double definition.
'murphy's' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'coat?' is the second definition.
(jacket is a kind of coat)
Can you help me to learn more?
(Other definitions for jacket that I've seen before include "Outer garment or casing" , "Record sleeve" , "Blazer" , "Short hip-length coat" , "in which King Edward got very hot" .)
