Power tending to make one draconian (8)
I believe the answer is:
punitive
'draconian' is the definition.
Although both the answer and definition are adjectives, I cannot see how one could define the other.
'power tending to make one' is the wordplay.
I cannot really understand how this works, but
'power' could be 'p' and 'p' is found in the answer.
'one' could be 'un' (I've seen this in other clues) and 'un' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for punitive that I've seen before include "very demanding" , "Severe and retaliatory" , "Inflicting penalty for an offence" , "Intended to inflict punishment" , "Penal; crippling" .)
