Masses sent out for appraisal (10)
I believe the answer is:
assessment
'appraisal' is the definition.
('assessment' can be a synonym of 'appraisal')
'masses sent out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'masses'+'sent'='massessent'
'massessent' with letters rearranged gives 'ASSESSMENT'.
'for' acts as a link.
(Other definitions for assessment that I've seen before include "rating" , "Process of valuation" , "Evaluation, estimation" , "Survey" , "Opinion" .)
