Diane Ladd leaves little to confuse (5)
I believe the answer is:
addle
'confuse' is the definition.
(addling is a kind of confusing)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for addle that I've seen before include "Confuse; go off" , "(Of eggs) turn bad" , "Scramble" , "Confuse - decay" , "Make rotten" .)
