Aunt lambasted demonstration, as you'd expect (9)
I believe the answer is:
naturally
'you'd expect' is the definition.
I can't tell whether this definition defines the answer.
'aunt lambasted demonstration' is the wordplay.
I cannot really see how this works, but
an anagram of 'aunt' is 'natu' which is located in the answer.
'demonstration' could be 'rally' (I've seen this in another clue) and 'rally' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'as' is the link.
Can you help me to learn more?
(Other definitions for naturally that I've seen before include "as anticipated" , "it goes without saying" , "without medical assistance" , "Occurring normally, not artificially" , "Without artificial help" .)
