Translation of "definite" into Persian

There was a little talk, and the details were definitely arranged.

بعدا، پس از مذاکره لازم، که همهچیز در ضمن آن روشن گردید،

there also exists a definite and well known, but quite false, conception.

نیز روایت معین و معروف همگان که با واقعیت به کلی مغایر است وجود دارد.

This sounds somewhat less definitive an end than I had expected.

اين نسبت به اون پاياني که انتظار داشتم ، به قدري قاطع تره.
