Put pressure on contract, if you don’t mind (6)
I believe the answer is:
please
'if you don't mind' is the definition.
(I've seen this before)
'put pressure on contract' is the wordplay.
I cannot really understand how this works, but
'pressure' could be 'p' (abbreviation) and 'p' is found in the answer.
'contract' could be 'lease' (leasing is a kind of contracting) and 'lease' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for please that I've seen before include "Delight, gladden" , "Polite request - make someone happy" , "Make happy or glad" , "Delight, satisfy" , "Give satisfaction to" .)
