Defamatory text (5)
I believe the answer is:
libel
'defamatory text' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for libel that I've seen before include "Written defamation" , "False and malicious publication to defame" , "Actionable words" , "Defame in writing" , "false report" .)
