Bony Lee's talk disrupted (8)
I believe the answer is:
skeletal
'bony' is the definition.
(synonyms)
'lee's talk disrupted' is the wordplay.
'disrupted' indicates anagramming the letters.
'lees'+'talk'='leestalk'
'leestalk' is an anagram of 'SKELETAL'.
(Other definitions for skeletal that I've seen before include "Comprising just the bare bones" , "Bony, gaunt" , "Dreadfully thin" , "reduced to a minimum" , "Very thin, emaciated" .)
