Report heard at a certain level (6)
I believe the answer is:
'level' is the definition.
'report heard at a certain' is the wordplay.
I cannot really understand how this works, but
'heard' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
'report' could be 'story' (story is a kind of report) and 'story' is located in the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for storey that I've seen before include "rooms on one level" , "Tier of a building" , "Oyster (anag) -- level" , "Layer of house" , "part of the building" .)
