odium

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

'great unpopularity' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'quietly leaves the podium' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'leaves' is a deletion indicator.
'podium' with 'p' removed is 'ODIUM'.

'in' acts as a link.

Can you help me to learn more?
