One's turn to leave cash for a writer (5)
I believe the answer is:
gogol
'a writer' is the definition.
(I've seen this before)
'one's turn to leave cash' is the wordplay.
'one's turn' becomes 'go' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' means one lot of letters go next to another.
'leave' becomes 'go'.
'cash' becomes 'l' (The pound sterling symbol is an elaborate L).
'go'+'go'+'l'='GOGOL'
'for' is the link.
Can you help me to learn more?
(Other definitions for gogol that I've seen before include "Nikolai ---, Gov't Inspector author" , "The Government Inspector author" , "Russian author/playwright" , "Russian novelist" , "Nineteenth century Russian author" .)
