No tea given out (8)
I believe the answer is:
negative
'no' is the definition.
(I've seen this before)
'tea given out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'tea'+'given'='teagiven'
'teagiven' anagrammed gives 'NEGATIVE'.
(Other definitions for negative that I've seen before include "Early form of photo" , "Expressing or implying denial or refusal" , "Defeatist" , "Less than positive" , "Film with images reversed" .)
