Perhaps Edwin receives two papers with currently moving material (9)
I believe the answer is:
driftwood
'perhaps edwin receives two papers' is the definition.
I can't judge whether this definition defines the answer.
'with currently moving material' is the wordplay.
'with' is a charade indicator (letters next to each other).
'currently moving' becomes 'drift' (I can't explain this - if you can you should give a lot more credence to this answer).
'material' becomes 'wood' (wood is a kind of material).
'drift' put next to 'wood' is 'DRIFTWOOD'.
Can you help me to learn more?
(Other definitions for driftwood that I've seen before include "Flotsam" , "items washed up?" , "Timber washed up by sea" , "Washed up pieces of tree" , "Timber washed ashore" .)
