aught

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

'anything' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for aught that I've seen before include "Anything (Shakespearean)" , "Anything at all (archaic)" , "Emphatically anything" , "Nothing" .)

I've seen this clue in the Evening Standard.
