Discovered loading bay (4)
I believe the answer is:
cove
'bay' is the definition.
(I've seen this in another clue)
'discovered loading' is the wordplay.
'COVE' is hidden in amongst the letters.
But, I am not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for cove that I've seen before include "Small bay or coastal inlet" , "Small bay or slangy man" , "Small bay or Dickensian chap" , "A small inlet or estuary" , "A small sea inlet or slangy man" .)
