Laze round holding nothing (4)

I believe the answer is:

zero

'nothing' is the definition.
(I know that nothing can be written as zero)

'laze round holding' is the wordplay.
'holding' says the answer is hidden in the clue.
'ZERO' is hidden within 'laze round'.

(Other definitions for zero that I've seen before include "Nought, the figure 0" , "Nothing; freezing point (in degrees centigrade)" , "Very bad visibility" , "ending as nothing too" , "No amount at all" .)

I've seen this clue in The Guardian.
