A man will love such recognition (5)
I believe the answer is:
hello
'recognition' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'a man will love' is the wordplay.
'a man' becomes 'he' (he refers to a man).
'will' becomes ''ll' (contracted form, as in 'he'll' - 'he will').
'love' becomes 'o' (love means zero in tennis).
'he'+'ll'+'o'='HELLO'
'such' is the link.
Can you help me to learn more?
(Other definitions for hello that I've seen before include "glossy magazine" , "Meeting greeting" , "royals dominate its pages?" , "Publication" , "Conventional word of greeting" .)
