Reportedly bait papers marked by sensationalism (5)
I believe the answer is:
lurid
'marked by sensationalism' is the definition.
(I've seen this in another clue)
'reportedly bait papers' is the wordplay.
I cannot quite see how this works, but
'papers' could be 'id' (identifying documents are one's 'papers') and 'id' is present in the answer.
The remaining letters 'lur' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lurid that I've seen before include "In shocking detail" , "Grim" , "In glaring colours, shockingly vivid" , "In vivid detail" , "Glaring in colour, shockingly vivid" .)
