Unmoved rubbish at each tip (9)
I believe the answer is:
apathetic
'unmoved' is the definition.
(thesaurus)
'rubbish at each tip' is the wordplay.
'rubbish' indicates an anagram (a poor quality or rubbish spelling of the letters).
'at'+'each'+'tip'='ateachtip'
'ateachtip' anagrammed gives 'APATHETIC'.
(Other definitions for apathetic that I've seen before include "Indifferent - without emotion" , "Not interested" , "past caring?" , "without interest" , "showing no enthusiasm" .)
