False part of folio omitted from professor's academic writing (10)
I believe the answer is:
prosthesis
'false part' is the definition.
(I've seen this before)
'professor's academic writing' is the wordplay.
'professor's academic' becomes 'pros' (I can't justify this - if you can you should believe this answer much more).
'writing' becomes 'thesis' (thesis is a kind of writing).
'pros'+'thesis'='PROSTHESIS'
'of folio omitted from' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for prosthesis that I've seen before include "False part" , "Part replacement" , "This may supply missing part" , "artificial substitute" , "what can help a handicapped person" .)
