Salesman doesn't tell the truth when giving answers (7)
I believe the answer is:
replies
'giving answers' is the definition.
'replies' can be an answer for 'answers' (to reply is to give an answer). I'm not sure about the 'giving' bit.
'salesman doesn't tell the truth' is the wordplay.
'salesman' becomes 'rep' (sales rep).
'doesn't tell the truth' becomes 'lies' (I've seen this in another clue).
'rep'+'lies'='REPLIES'
'when' acts as a link.
Can you help me to learn more?
(Other definitions for replies that I've seen before include "Answers" , "Responds" , "Reacts verbally" .)
