Showed a documentary of Partition by writer (8)
I believe the answer is:
screened
'showed a documentary' is the definition.
'screened' can be an answer for 'showed' (screening is a kind of showing). I am not sure about the 'a documentary' bit.
'partition by writer' is the wordplay.
'partition' becomes 'screen' (screen is a kind of partition).
'by' is a charade indicator (letters next to each other).
'writer' becomes 'ed' (I've seen this in other clues**).
'screen'+'ed'='SCREENED'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for screened that I've seen before include "Subjected to checks" , "shown on TV" , "Tested for disease or infection" , "Carefully checked" , "Involved in selection process" .)
