On the street, a loud cry to increase sales? (5)
I believe the answer is:
boost
'increase sales?' is the definition.
'boost' can be an answer for 'increase' (boosting is a kind of increasing). I am unsure of the 'sales?' bit.
'on the street a loud cry' is the wordplay.
'on' means one lot of letters go next to another.
'the street' becomes 'st'.
'a loud cry' becomes 'boo' (I have seen 'Cry of contempt ' mean 'boo' so perhaps 'cry' could also mean 'boo'. I am not sure about the 'loud' bit.**).
'st' put after 'boo' is 'BOOST'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for boost that I've seen before include "Uplift" , "Raise" , "Shot in the arm" , "Encourage or increase" , "Promote" .)
