Broadcasts not the first but the last word (5)
I believe the answer is:
adios
'the last word' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'broadcasts not the first' is the wordplay.
'broadcasts' becomes 'radios' (I've seen this in another clue).
'not the first' means to remove the first letter.
'radios' with its first letter taken away is 'ADIOS'.
'but' acts as a link.
Can you help me to learn more?
(Other definitions for adios that I've seen before include "Bye!" , "Adieu, arrivederci" , "Farewell amigo!" , "So long, amigo" , "Bye-bye (amigo)" .)
