At the end of the day, estate agent showing first house gets positive response (4)
I believe the answer is:
yeah
'positive response' is the definition.
(I've seen this before)
'at the end of the day estate agent showing first house' is the wordplay.
'at the end of' suggests the final letters.
'agent showing' becomes 'a' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'first house' becomes 'h' (ast letter of 'house').
The final letters of 'day estate' are 'ye'.
'ye'+'a'+'h'='YEAH'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for yeah that I've seen before include "Casual form of yes" , "casual agreement" , "Definitely (informal)" , "Certainly" , "Informal agreement" .)
