Provide funding for riverside function, we hear (8)

Ross

I believe the answer is:

bankroll

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

'provide funding' is the definition.
I can't judge whether this definition defines the answer.

'riverside function we hear' is the wordplay.
'riverside' becomes 'bank' (I've seen this in another clue).
'function' becomes 'role' (synonyms).
'we hear' shows a homophone (sound like).
'role' sounds like 'roll'.
'bank'+'roll'='BANKROLL'

'for' acts as a link.

Can you help me to learn more?

(Other definitions for bankroll that I've seen before include "Fund" , "keep afloat?" , "Provide finance for" .)
