Convince that you'll give notice (5,2,5)
I believe the answer is:
leave no doubt
'convince that you'll' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'give notice' is the wordplay.
I cannot quite understand how this works, but
'give' could be 'leave' (leaving is a kind of giving) and 'leave' is found in the answer.
The remaining letters 'nodoubt' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
