Mount is in a bad way (5)
I believe the answer is:
sinai
'mount' is the definition.
(I've seen this before)
'is in a bad way' is the wordplay.
'bad way' indicates an anagram (I've seen this in other clues).
'is'+'in'+'a'='isina'
'isina' anagrammed gives 'SINAI'.
(Other definitions for sinai that I've seen before include "Mountainous peninsula in Egypt" , "Deserted area" , "Mountainous Egyptian peninsula" , "Biblical mount" , "Mount on which Moses received the Ten Commandments" .)
