Answers salesperson with false statements (7)
I believe the answer is:
replies
'answers' is the definition.
('reply' can be a synonym of 'answer')
'salesperson with false statements' is the wordplay.
'salesperson' becomes 'rep' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'false statements' becomes 'lies' (lie is a kind of false statement).
'rep'+'lies'='REPLIES'
(Other definitions for replies that I've seen before include "Reacts verbally" , "Responds" , "Answers" .)
