Record album with explosive opening! (4)
I believe the answer is:
help
'record album' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'with explosive opening' is the wordplay.
'with' means one lot of letters go next to another.
'explosive' becomes 'he' (abbreviation for high explosive).
'opening' becomes 'lp' (I can't explain this - if you can you should believe this answer much more).
'he'+'lp' is 'HELP'.
Can you help me to learn more?
(Other definitions for help that I've seen before include "SOS, mayday" , "Guide" , "Lend a hand" , "Contribute to the success of" , "I can't cope" .)
