In a daze, possibly puts nothing right (6)
I believe the answer is:
stupor
'in a daze' is the definition.
(I've seen this before)
'possibly puts nothing right' is the wordplay.
'possibly' is an anagram indicator.
'nothing' becomes 'o' (looks like zero - 0).
'right' becomes 'R' (common abbreviation).
'puts' with letters rearranged gives 'stup'.
'stup'+'o'+'r'='STUPOR'
(Other definitions for stupor that I've seen before include "State of near unconsciousness" , "State of dazedness or bemusement" , "Semi-conscious state" , "Inertia results!" , "Dazed or unconscious condition, sometimes caused by alcohol" .)
