Original sound, nine implications (9)

I believe the answer is:

innuendos

I'm a little stuck... Click here to teach me more about this clue!

'implications' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Maybe they are linked in a way I don't understand?

'original sound nine' is the wordplay.
'original' indicates an anagram.
'sound'+'nine'='soundnine'
'soundnine' is an anagram of 'INNUENDOS'.

Can you help me to learn more?
