Tea-time's special for judge (8)
I believe the answer is:
estimate
'judge' is the definition.
(I've seen this before)
'tea-time's special' is the wordplay.
'special' is an anagram indicator.
'tea'+'times'='teatimes'
'teatimes' anagrammed gives 'ESTIMATE'.
'for' is the link.
(Other definitions for estimate that I've seen before include "Judgement of approximate value or size" , "damage" , "Reckon, guess" , "Likely amount" , "Gauge - approximation" .)
