Entertaining event: concert with piano at end (4)
I believe the answer is:
romp
'end' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'entertaining event concert with piano' is the wordplay.
'entertaining event concert' becomes 'rom' (I can't justify this - if you can you should believe this answer much more).
'with' means one lot of letters go next to another.
'piano' becomes 'p' (musical abbreviation).
'rom'+'p'='ROMP'
'at' is the link.
Can you help me to learn more?
(Other definitions for romp that I've seen before include "Light-hearted film; easy victory" , "Dance" , "Frolic" , "High jinks" , "Play roughly/energetically; easy victory" .)
