Poor state, dire, is par sadly (9)
I believe the answer is:
disrepair
'poor state' is the definition.
(I've seen this before)
'dire is par sadly' is the wordplay.
'sadly' indicates an anagram.
'dire'+'is'+'par'='direispar'
'direispar' is an anagram of 'DISREPAIR'.
(Other definitions for disrepair that I've seen before include "In need of mending" , "Poor condition" , "state of neglect" , "Poor working order" , "poor state" .)
