Give US intelligence a ring and say hello (4)
I believe the answer is:
ciao
'say hello' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?
'give us intelligence a ring' is the wordplay.
I cannot quite see how this works, but
'intelligence' could be 'cia' (Central Intelligence Agency) and 'cia' is present in the answer.
'ring' could be 'o' (letter resembling a ring) and 'o' is located in the answer.
No letters remain.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for ciao that I've seen before include "Italian salutation" , "See you later in Rome?" , "Hello and goodbye to the Italians" , "Buongiorno o arrivederci" , "Italian hello or goodbye" .)
