Reports about Facebook owner installed into medical devices (10)
I believe the answer is:
statements
'reports' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps there's a link between them I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for statements that I've seen before include "Accounts made to police" , "Affirmations" , "Assertions" .)
