Well, I’m polite? (8,2)
I believe the answer is:
gracious me
'well i'm' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'polite?' is the wordplay.
I cannot really understand how this works, but
'polite?' could be 'gracious' (similar in meaning) and 'gracious' is found in the answer.
The remaining letters 'me' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gracious me that I've seen before include "Gordon Bennett" , "Mamma Mia!" .)
