Liberal goes out with an uplifting entertainer (9)
I believe the answer is:
ballerina
'entertainer' is the definition.
(ballerina is a kind of entertainer)
'liberal goes out with an uplifting' is the wordplay.
'goes out' indicates anagramming the letters.
'with' means one lot of letters go next to another.
'uplifting' says the letters should be written backwards.
'an' back-to-front is 'na'.
'liberal' is an anagram of 'balleri'.
'balleri'+'na'='BALLERINA'
(Other definitions for ballerina that I've seen before include "Dancers" , "agile performer" , "lass good at splits?" , "Danseuse" , "girl on point duty" .)
