Try and try again? Absolutely! (4,4)
I believe the answer is:
hear hear
'again? absolutely' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'try and try' is the wordplay.
'try' becomes 'hear' ('hear' can be a synonym of 'try').
'and' says to put letters next to each other.
'try' becomes 'hear' ('hear' can be a synonym of 'try').
'hear'+'hear'='HEAR HEAR'
Can you help me to learn more?
(Other definitions for hear hear that I've seen before include "I totally agree" , "Listen, listen - it's approval" , "Jolly good!" , "That's right" , "Exclamation of approval" .)
