Southern sprite has power to elevate. It's no recommendation (4-6)
I believe the answer is:
self-praise
'no recommendation' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'southern sprite has power to elevate' is the wordplay.
'southern' becomes 's' (abbreviation).
'sprite' becomes 'elf' (an elf is a sprite).
'has' means one lot of letters go next to another.
'power' becomes 'p' (symbol in physics).
'to elevate' becomes 'raise' ('raise' can be a synonym of 'elevate').
's'+'elf'+'p'+'raise'='SELF-PRAISE'
'it's' acts as a link.
Can you help me to learn more?
(Another definition for self-praise that I've seen is " No honour?".)
