Aim to annoy, which does make things dicey (8)
I believe the answer is:
endanger
'does make things dicey' is the definition.
I can't tell whether this definition defines the answer.
'aim to annoy' is the wordplay.
'aim' becomes 'end' (both can mean a goal or purpose).
'to annoy' becomes 'anger' (I've seen this before).
'end'+'anger'='ENDANGER'
'which' acts as a link.
Can you help me to learn more?
(Other definitions for endanger that I've seen before include "Put in peril" , "Threaten" , "Put in trouble" , "Hazard" , "Put in harm's way" .)
