Droppings are easy without even overalls (9)
I believe the answer is:
dungarees
'overalls' is the definition.
(I have seen 'Durable overalls ' mean 'dungarees' so perhaps 'overalls' could also mean 'dungarees')
'droppings are easy' is the wordplay.
'droppings' becomes 'dung' (synonyms).
'easy' becomes 'es' (I can't explain this - if you can you should believe this answer much more).
'dung'+'are'+'es'='DUNGAREES'
'without even' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for dungarees that I've seen before include "Work overalls" , "Overall" , "garment" , "protection at work" , "Overalls of cotton fabric" .)
