Final word from the cricket (3)
I believe the answer is:
bye
'final word' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'from the cricket' is the wordplay.
'from' becomes 'by'.
'the cricket' becomes 'e' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'by'+'e'='BYE'
Can you help me to learn more?
(Other definitions for bye that I've seen before include "Extra run in cricket" , "Reason not to play" , "Get one to advance to the next round without playing an opponent" , "See you" , "(Informal) valediction" .)
