'very many' is the definition.
'no end of' can be an answer for 'many' (I've seen this before). I'm not sure about the 'very' bit.

'number fed on bananas' is the wordplay.
'number' becomes 'no' (abbreviation for 'number').
'bananas' is an anagram indicator (informal term for mad).
'fed'+'on'='fedon'
'fedon' with letters rearranged gives 'endof'.
'no'+'endof'='NO END OF'

Can you help me to learn more?

(Another definition for no end of that I've seen is " Many".)

I've seen this clue in The Guardian.
