Mad dog's companion in The Sun? (10)
I believe the answer is:
englishman
This clue could be a double definition.
'mad dog's companion' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'sun?' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'in the' is the link.
Can you help me to learn more?
(Other definitions for englishman that I've seen before include "European" , "For example, Ralph Rackstraw" , "Native" , "Bennett's abroad (Burgess)" , "E.g. Coward's idiot at 12" .)
