A basket an Indian has left behind (5)
I believe the answer is:
creel
'a basket' is the definition.
(basket for holding fish)
'an indian has left behind' is the wordplay.
'an indian' becomes 'cree' (Cree is an example).
'has left behind' becomes 'l' (I can't explain this - if you can you should give a lot more credence to this answer).
'cree'+'l'='CREEL'
Can you help me to learn more?
(Other definitions for creel that I've seen before include "Wicker basket for fish" , "Angler's wicker basket" , "Wickerwork basket" , "lobster basket" , "Bobbin rack" .)
