Early morning exhortation to Polish? (4,3,5)
I believe the answer is:
rise and shine
'early morning exhortation' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'polish?' is the wordplay.
I cannot really see how this works, but
'polish?' could be 'shine' (synonyms) and 'shine' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for rise and shine that I've seen before include "as star may in evening" , "Cheerful (!) invitation to vacate one's bed in the morning" , "Exhortation to get out of bed" , "Bounce out of bed" , "as will the sun bright and early?" .)
