So - nothing's cleared off? Lazy creep! (5)
I believe the answer is:
sidle
'creep' is the definition.
(thesaurus)
'so nothing's cleared off? lazy' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'cleared off?' indicates named letters should be taken away.
'lazy' becomes 'idle' ('idle' can be similar in meaning to 'lazy').
'so' with 'o' taken out is 's'.
's'+'idle'='SIDLE'
(Other definitions for sidle that I've seen before include "Slide (anag.)" , "Make cautious progress" , "Walk stealthily" , "Walk obliquely" , "Slink, creep, sneak" .)
