Possibly read about a race being dishonourably abandoned (6)
I believe the answer is:
ratted
'dishonourably abandoned' is the definition.
Although both the answer and definition are past participle verbs, I can't see how they can define each other.
'possibly read about a race' is the wordplay.
'possibly' is an anagram indicator.
'about' is an insertion indicator.
'a race' becomes 'tt'.
'read' with letters rearranged gives 'raed'.
'raed' placed around 'tt' is 'RATTED'.
'being' is the link.
Can you help me to learn more?
(Other definitions for ratted that I've seen before include "Broke promise in treacherous or rodent style" , "Deserted; very drunk" , "Betrayed like a rodent" , "Deserted the side, rodent-like" , "Betrayed or informed, the rodent" .)
