Got back engraved bust right away (7)
I believe the answer is:
avenged
'got back' is the definition.
'engraved bust right away' is the wordplay.
I cannot really understand how this works, but
'away' could be 'a' (abbreviation as used in sports fixtures) and 'a' is located in the answer.
The remaining letters 'venged' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for avenged that I've seen before include "Took reprisals for" , "Inflicted retribution for (a wrong)" , "being paid back" , "Got back at" .)
