Evaluation of men’s assets uncommon (10)
I believe the answer is:
assessment
'evaluation' is the definition.
(I've seen this before)
'men's assets uncommon' is the wordplay.
'uncommon' indicates anagramming the letters.
'mens'+'assets'='mensassets'
'mensassets' anagrammed gives 'ASSESSMENT'.
'of' is the link.
(Other definitions for assessment that I've seen before include "amount to be paid" , "Process of valuation" , "Review" , "Opinion" , "rating" .)
