Pauper gets depressed - also unacceptable (4-3-3)
I believe the answer is:
down-and-out
'pauper' is the definition.
(thesaurus)
'depressed also unacceptable' is the wordplay.
'depressed' becomes 'down' (synonyms).
'also' becomes 'and' (both can mean in addition).
'unacceptable' becomes 'out' (out can mean incorrect or inappropriate).
'down'+'and'+'out'='DOWN-AND-OUT'
'gets' acts as a link.
(Other definitions for down-and-out that I've seen before include "Impoverished (and unconscious?)" , "Impoverished - destitute person" .)
