Bishop has deficiency, predicament from which there's no getting away (5,4)
I believe the answer is:
black hole
'bishop has deficiency predicament from which there's no getting away' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'bishop has deficiency predicament' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'has' means one lot of letters go next to another.
'deficiency' becomes 'lack' (synonyms).
'predicament' becomes 'hole' (I've seen this in another clue).
'b'+'lack'+'hole'='BLACK HOLE'
Can you help me to learn more?
