Sort of cap for a bonehead? (5)
I believe the answer is:
skull
This might be a double definition.
'sort of cap' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'a bonehead?' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for skull that I've seen before include "Bony frame of head ..." , "Bony part of head" , "Part of skeleton" , "Head structure" , "Brain casing" .)
