Dictator left abandoned in disgrace (5)
I believe the answer is:
stain
'disgrace' is the definition.
(thesaurus)
'dictator left abandoned in' is the wordplay.
I cannot really see how this works, but
'in' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for stain that I've seen before include "Satin (anag.)" , "Blotch on satin" , "Dirty mark; dye" , "Discolouration" , "Discoloured patch" .)
