Bashed on a cut (10)
I believe the answer is:
persevered
'bashed' is the definition.
Although both the answer and definition are past participle verbs, I don't see how one could define the other.
'on a cut' is the wordplay.
'on' is a charade indicator (letters next to each other).
'a' becomes 'per' (eg 'one a day' means 'one per day').
'cut' becomes 'severed' (similar in meaning).
'per'+'severed' is 'PERSEVERED'.
Can you help me to learn more?
(Other definitions for persevered that I've seen before include "Was not deterred" , "Kept going" , "didn't give up" .)
