Strategy culminates in bloke booming (8)
I believe the answer is:
plangent
'booming' is the definition.
(I've seen this before)
'strategy culminates in bloke' is the wordplay.
I cannot quite see how this works, but
'strategy' could be 'plan' (a strategy is a plan or tactic) and 'plan' is found within the answer.
'bloke' could be 'gent' (both can mean a man) and 'gent' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for plangent that I've seen before include "booming" , "Mournful-sounding" , "information to put around" , "Noisy" , "Loud and sad" .)
