Saw little, nothing’s approved (6)
I believe the answer is:
looked
'saw' is the definition.
(both can mean viewed)
'little nothing's approved' is the wordplay.
'little' becomes 'l' (abbreviation for little).
'nothing' becomes 'o' (looks like zero - 0).
'approved' becomes 'oked' ('ok' can be a synonym of 'approve').
'l'+'o'+'oked'='LOOKED'
(Other definitions for looked that I've seen before include "Directed one' s gaze towards" , "Directed one's gaze towards" , "Appeared" , "Direct one's gaze towards" .)
