Left one fellow taking answer as written (8)
I believe the answer is:
literary
'written' is the definition.
(thesaurus)
'left one fellow taking answer' is the wordplay.
I cannot really understand how this works, but
'left' could be 'l' (common abbreviation) and 'l' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
'answer' could be 'a' (abbreviation eg in Q and A) and 'a' is present in the answer.
'fellow' could be 'terry' (Terry is a man's name) and 'terry' is present in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'as' is the link.
Can you help me to learn more?
(Other definitions for literary that I've seen before include "Concerning written material" , "Well-read" , "Learned" , "Type of writing of artistic merit" , "Bookish" .)
