Please check the next sentences:
1- A - She is incompetent and lazy . B -What's your reason to say that?
2 A - The president is likely to resign. B - What's your reason to say that?
I would like to know if this "what's your reason to.." is an idiomatic expression in English.
The question I intend to ask by using "what's your reason to ..." is something like "what are your arguments?" " what is your reasoning behind that statement?" "What evidence do you have to support that?".
If somebody understood the intended meaning of my sentences,feel free to rewrite them to fit natural,idiomatic English sentences.
No. Idiomatic English is eg What's your reason for saying that? eg Why do you say that?
