Run into hamper that’s in poor condition (10)
I believe the answer is:
ramshackle
'in poor condition' is the definition.
(I've seen this before)
'run into hamper' is the wordplay.
'run into' becomes 'ram' (I've seen this in another clue).
'hamper' becomes 'shackle' (synonyms).
'ram'+'shackle'='RAMSHACKLE'
'that's' is the link.
(Other definitions for ramshackle that I've seen before include "Broken-down" , "Rickety - derelict" , "Badly-organised" , "Decrepit" , "Tumbledown" .)
