Praise Victor, a kinky nut (5)
I believe the answer is:
vaunt
'praise' 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 can't see?
'victor a kinky nut' is the wordplay.
'victor' becomes 'V' (phonetic alphabet: alpha, bravo, charlie etc.).
'kinky' indicates anagramming the letters.
'nut' anagrammed gives 'unt'.
'v'+'a'+'unt'='VAUNT'
Can you help me to learn more?
(Other definitions for vaunt that I've seen before include "Talk boastfully of" , "crow" , "Show off" , "Trumpet" , "Boast about (something), often excessively" .)
