Shops expect increase in salary to be announced (7)
I believe the answer is:
betrays
'shops' is the definition.
(I know this)
'expect increase in salary to be announced' is the wordplay.
'expect' becomes 'bet' (I can't justify this - if you can you should believe this answer much more).
'increase in salary' becomes 'raise' (getting a raise is getting an increased salary).
'to be announced' shows a homophone (sound like).
'raise' sounds like 'rays'.
'bet'+'rays'='BETRAYS'
Can you help me to learn more?
(Other definitions for betrays that I've seen before include "Shows unintentionally, say feelings" , "Double-crosses" , "Sells" , "shops" , "Gives away" .)
