stony-broke

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

'without any green' is the definition.
I can't tell whether this defines the answer.

'entry books unfortunately' is the wordplay.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'entry'+'books'='entrybooks'
'entrybooks' anagrammed gives 'STONY-BROKE'.

Can you help me to learn more?

(Other definitions for stony-broke that I've seen before include "Penniless" , "Utterly skint" .)
