Hex (5)

Ross

I think it could be either:

spell

curse

'hex' is the definition.
(synonyms)

This is all the clue.

(Other definitions for curse that I've seen before include "Cuss" , "Wish harm on" , "Malediction or expletive" , "Oath or a call for evil to come upon person" , "Wish evil upon" .)

I've seen this clue in The Times, the LA Times, The Star Tribune and The Sunday Times.
