Father turning Paris off with a liberal evaluation (9)
I believe the answer is:
appraisal
'evaluation' is the definition.
(I've seen this before)
'father turning paris off with a liberal' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'turning' says the letters should be written in reverse.
'off with' indicates an anagram.
'liberal' becomes 'l' (abbreviation).
'pa' backwards is 'ap'.
'paris' anagrammed with 'a' gives 'praisa'.
'ap'+'praisa'+'l'='APPRAISAL'
(Other definitions for appraisal that I've seen before include "judgment" , "valuation" , "Evaluation - papal airs (anag)" , "judgement" , "Formal assessment of an employee's performance" .)
