Confident, furthermore, entering business (3-2)
I believe the answer is:
can-do
'confident' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'furthermore entering business' is the wordplay.
'furthermore' becomes 'and' (I can't justify this - if you can you should believe this answer much more).
'entering' indicates putting letters inside.
'business' becomes 'co'.
'and' placed inside 'co' is 'CAN-DO'.
Can you help me to learn more?
(Other definitions for can-do that I've seen before include "Positive-thinking" , "Positive" , "Showing willingness to get the job done" .)
