Very little money provided by New York to support a writer (1,5)

'very little money' is the definition.
(a penny is a small amount of money)

'new york to support a writer' is the wordplay.
'new york' becomes 'ny'.
'to support' is a charade indicator (letters next to each other) (in a down clue, some letters hold others up).
'writer' becomes 'pen' (something which writes).
'a'+'pen'='apen'
'ny' after 'apen' is 'A PENNY'.

'provided by' acts as a link.
