Unfinished section of minster creating hazard (6)

I believe the answer is:

chance

I'm a little stuck... Click here to teach me more about this clue!

'hazard' is the definition.
(hazard can mean chance)

I cannot understand how the rest of the clue works.

(Other definitions for chance that I've seen before include "I wish (but it won't happen!)" , "part of Monopoly" , "The way things happen, luck" , "Happenstance" , "Odds" .)

I've seen this clue in The Times.
