Fair to middling fortune put up by a rebel outfit (9)
I believe the answer is:
tolerable
'fair to middling' is the definition.
(thesaurus)
'fortune put up by a rebel outfit' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
an anagram of 'rebel' is 'erble' which is within the left over letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tolerable that I've seen before include "Bearable" , "Fairly good" , "Passable" , "may be accepted?" , "Acceptable" .)
