Duke with hatred creates hazard (6)
I believe the answer is:
danger
'hazard' is the definition.
(a hazard is something dangerous)
'duke with hatred' is the wordplay.
I cannot really see how this works, but
'duke' could be 'd' (abbreviation) and 'd' is located in the answer.
The remaining letters 'anger' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'creates' acts as a link.
Can you help me to learn more?
(Other definitions for danger that I've seen before include "Peril, jeopardy" , "Menace" , "Peril, exposure to harm" , "Insecurity" , "Red flag, for example" .)
