American drafted piece of writing following study (9)
I believe the answer is:
conscript
'american drafted' is the definition.
(as in being drafted into the US army)
'writing following study' is the wordplay.
'writing' becomes 'script' (script is a kind of writing).
'following' means one lot of letters go next to another.
'study' becomes 'con' (con can informally mean to study).
'script' after 'con' is 'CONSCRIPT'.
'piece of' acts as a 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 conscript that I've seen before include "One drafted into the forces" , "Draftee" , "Compulsorily enlisted person" , "Enlist compulsorily" , "Enrol for compulsory service" .)
