Turn and leave one learning to be a writer (5)

I believe the answer is:
gogol
'a writer' is the definition.
(author Nikolai Gogol)
'turn and leave one learning' is the wordplay.
'turn' becomes 'gogo' (I can't explain this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'leave' says to take the initial letters (I've seen 'left of' mean this (the leftmost letter in the word)).
The first letter of 'learning' is 'l'.
'gogo'+'l'='GOGOL'
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for gogol that I've seen before include "Russian author/playwright" , "Russian novelist" , "Dead Souls Russ. author" , "Russian writer" , "Nikolai ---, Gov't Inspector author" .)
