Evaluation of the Paris trip a chum is about to give (9)
I believe the answer is:
'evaluation' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for appraisal that I've seen before include "judgement" , "judgment" , "Evaluation - papal airs (anag)" , "rating" , "Formal assessment of an employee's performance" .)
