Play joke on editor, suggesting it's written in a puzzling way (5)
I believe the answer is:
coded
'it's written in a puzzling way' is the definition.
I can't tell whether this defines the answer.
'play joke on editor' is the wordplay.
'play joke on' becomes 'cod' (I've seen this before).
'editor' becomes 'ed' (abbreviation).
'cod'+'ed'='CODED'
'suggesting' is the link.
Can you help me to learn more?
(Other definitions for coded that I've seen before include "Enciphered" , "Encrypted, prearranged for secrecy" .)
