Hex, jinx (5)

I believe the answer is:

curse

This clue is a double definition.

'hex' is the first definition.
(synonyms)

'jinx' is the second definition.
(synonyms)

(Other definitions for curse that I've seen before include "Blasphemy" , "Execrate" , "Invocation of evil; swear" , "Evil spell - oath" , "Imprecation or oath" .)

I've seen this clue in The Times.
