With a certain amount of disputing, made an application (3,2)
I believe the answer is:
put in
'with a certain' is the definition.
I can't judge whether this definition defines the answer.
'amount of disputing made an application' is the wordplay.
'PUT IN' is hidden within the letters.
But, I am not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for put in that I've seen before include "Deposit" , "being asked to bat" , "Rugby throw to a set scrum" , "Submit" , "Insert" .)
