One who might value classes Sorbonne hosts (8)
I believe the answer is:
assessor
'one who might' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'value classes sorbonne hosts' is the wordplay.
'hosts' indicates the answer is hidden within the clue.
'ASSESSOR' is hidden in the letters of 'value classes sorbonne'.
Can you help me to learn more?
(Other definitions for assessor that I've seen before include "One who estimates or fixes value" , "inspector" , "Legal adviser" , "Evaluator, estimator" , "Judge of quality" .)
