Set straight communist about conflicts without borders (7)
I believe the answer is:
righted
'set' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs sometimes define each other.
'straight communist about conflicts without borders' is the wordplay.
'straight communist' becomes 'red' (red can informally mean communist. I am not sure about the 'straight' bit.).
'about' means one lot of letters goes inside another.
'conflicts' becomes 'fights' (fight is a kind of conflict).
'without borders' means to look at the middle letters (the letters on the sides of the word are removed).
The middle letters of 'fights' are 'ight'.
'red' enclosing 'ight' is 'RIGHTED'.
Can you help me to learn more?
(Another definition for righted that I've seen is " Made reparation".)
