It'll help you understand scam message (7)
I believe the answer is:
context
'it'll help you understand' is the definition.
I can't judge whether this definition defines the answer.
'scam message' is the wordplay.
'scam' becomes 'con' (I've seen this in another clue).
'message' becomes 'text' (text message).
'con'+'text'='CONTEXT'
Can you help me to learn more?
(Other definitions for context that I've seen before include "Setting of discourse" , "what they relate to" , "Surrounding circumstances" , "Frame of reference" , "Surrounding setting" .)
