Trunk in which one keeps playing cards? (8)
I believe the answer is:
suitcase
'trunk in which one keeps playing cards?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'trunk in' is the wordplay.
I cannot really understand how this works, but
'trunk' could be 'case' (I've seen this before) and 'case' is found in the answer.
The remaining letters 'suit' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for suitcase that I've seen before include "that traveller may take" , "Type of holdall" , "A bit of baggage" , "Pack it to travel {8}" , "Item of luggage" .)
