Cold and miserable
This clue could be a double definition.
'cold' is the first definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'miserable' is the second definition.
'and' is the link.
Can you help me to learn more?
