Heavy going in Bermuda (3)
I believe the answer is:
mud
'heavy going' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'in bermuda' is the wordplay.
'in' indicates the answer is hidden within the clue.
'MUD' is hidden in the letters of 'bermuda'.
Can you help me to learn more?
(Other definitions for mud that I've seen before include "Adverse comments" , "Wet soil" , "Earth and water mixed" , "Liquid earth" , "Water-soaked soil" .)
