Bishop's most recent expression of annoyance (5)
I believe the answer is:
blast
'expression of annoyance' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'bishop's most recent' is the wordplay.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'most recent' becomes 'last' (the last in a list is the most recent).
'b'+'last'='BLAST'
Can you help me to learn more?
(Other definitions for blast that I've seen before include "Shoot" , "Strong gust of air" , "Severely criticise" , "Noise of explosion" , "Effect of explosion" .)
