Attempt to seize power company at an end (4)
I believe the answer is:
coup
'attempt' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'seize power company at an end' is the wordplay.
I cannot really see how this works, but
'power' could be 'p' (symbol in physics) and 'p' is found within the answer.
'company' could be 'co' (abbreviation) and 'co' is present in the answer.
A single letter 'u' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for coup that I've seen before include "Accomplishment, exploit" , "Brilliant and notable success" , "Brilliant success - seizure of government" , "rising" , "Brilliant stroke" .)
