Zero, nought (7)

I believe the answer is:

nothing

I believe this clue is a double definition.

'zero' is the first definition.
(synonyms)

'nought' is the second definition.
(synonyms)

(Other definitions for nothing that I've seen before include "A void" , "without object" , "unimportant or > unintelligible" , "Unimportant item" , "What Cordelia had to say" .)

I've seen this clue in The Guardian.
