Leave a mark on papers writer's put on top (7)
I believe the answer is:
impress
'leave a mark' is the definition.
(I've seen this before)
'papers writer's put on top' is the wordplay.
I cannot quite see how this works, but
'papers' could be 'press' (the newspaper industry) and 'press' is present in the answer.
'writer's' could be 'im' ('I am' referring to the writer of the clue) and 'im' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'on' is the link.
Can you help me to learn more?
(Other definitions for impress that I've seen before include "Slay" , "Make one's mark (on)" , "produce a profound effect" , "gain respect" , "Bowl over" .)
