Polite and appropriate, showing luggage from embassy? (10,3)
I believe the answer is:
diplomatic bag
'luggage from embassy?' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'polite and appropriate' is the wordplay.
I cannot really understand how this works, but
'appropriate' could be 'bag' (I've seen this in other clues) and 'bag' is found in the answer.
The remaining letters 'diplomatic' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'showing' acts as a link.
Can you help me to learn more?
(Other definitions for diplomatic bag that I've seen before include "Embassy mail sack" , "Embassy's mail container" , "One taking post abroad" , "Embassy mail pouch" .)
