Certainty and Mood in Embedded Claims
مطمئنم که نامه رسیده است. → asserted confidence. گمان میکنم نامه رسیده باشد. → conjecture.
How It Works
Read the holder of the attitude. مطمئنم که نامه رسیده است attributes certainty to the speaker through ـم. رسیده است is the embedded arrival claim. A report that someone is sure does not make the reporter independently sure.
Compare conjecture. گمان میکنم نامه رسیده باشد leaves arrival as a conjecture. The perfect subjunctive concerns completed arrival. It does not turn the completion into a future event merely because باشد has a present-shaped stem.
Allow a contextual alternative. فکر میکنم نامه رسیده است can present a more assertive thought; فکر میکنم نامه رسیده باشد can keep the event less settled. The difference depends on the speaker and discourse, not a compulsory ban on the indicative after thinking.
Separate confidence from proof. The speaker can be mistaken in either construction. None of these phrases assigns a numerical probability or guarantees a reliable source. A careful reader tracks who holds the belief, what event is evaluated and what evidence the passage supplies.
