Optative (2nd person)

The optative conveys the speaker's attitude of hope or wish directly oriented towards a person or a state of things.
When oriented to the addressee, the conditional form in -SA is used.
The overall effect is that of a very polite tentative question or request.

Chiroqni yoqsangiz.
Would you turn on the light?

Qani, bugun biznikiga kelsang?
How about that, would you not come us today?

Bizga bersangiz!
Would you give it to us?
