Last word from the cricket? (3)
I believe the answer is:
'last word' is the definition.
(word said before parting)
'from the cricket?' is the wordplay.
'from' becomes 'by' (by can mean from a particular person).
'the cricket?' becomes 'e' (I am not sure about this - if you are sure you should believe this answer much more).
Can you help me to learn more?
(Other definitions for bye that I've seen before include "Extra run in cricket" , "See you" , "Run not off bat" , "Reason not to play" , "Get one to advance to the next round without playing an opponent" .)
