Ignores protocol and erroneously includes item that doesn't hold any water (8)
I believe the answer is:
colander
'item that doesn't hold any water' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'ignores protocol and erroneously includes' is the wordplay.
'includes' says the answer is hidden in the clue.
'COLANDER' is hidden within 'ignores protocol and erroneously'.
Can you help me to learn more?
(Other definitions for colander that I've seen before include "found in the kitchen" , "Vessel for draining" , "Container for straining water from food" , "Utensil for draining vegetables" , "Kitchen sieve" .)
