He will get a ring and answer thus (5)
I believe the answer is:
hello
'he' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'will get a ring and answer thus' is the wordplay.
'will' becomes ''ll' (contracted form, as in 'he'll' - 'he will').
'get' is a charade indicator (letters next to each other).
'a ring' becomes 'o' (letter resembling a ring).
'and' means one lot of letters go next to another.
'answer thus' becomes 'he' (I can't explain this - if you can you should give a lot more credence to this answer).
'll'+'o' is 'llo'.
'llo' put after 'he' is 'HELLO'.
Can you help me to learn more?
(Other definitions for hello that I've seen before include "royals dominate its pages?" , "Conventional word of greeting" , "Conversation starter" , "Publication" , "A salutation" .)
