Inflammation from chin to ribs? (10)
I believe the answer is:
bronchitis
'inflammation' is the definition.
(thesaurus)
'from chin to ribs' is the wordplay.
'from' indicates an anagram (from the letters).
'chin'+'to'+'ribs'='chintoribs'
'chintoribs' anagrammed gives 'BRONCHITIS'.
(Other definitions for bronchitis that I've seen before include "Result of infection in respiratory tract" , "Respiratory disorder" , "Chest illness" .)
