Optative (1st person)
The optative conveys the speaker's attitude of hope or wish directly oriented towards a person or a state of things.
It is grammaticalized through suffixes depending on the person. For the speaker (the first person), the suffix is -AY (singular,
sometimes -AYIN), or -AYLIK (plural) if other persons than the speaker are also concerned, especially the addressee(s).
Bu kitobni olayin.
I would buy this book.
Qornim juda ochqadi, yuring birga ovqatlanaylik.
I am very hungry, let's go have a lunch together.
Where would we go?
Let's go now.
Dada, ertaga hayvonot bog'iga boraylik.
Dad, let's go tomorrow to the zoo.
The conditional suffix -SA added to the verb (in an independent phrase) may be also used with the same range of meanings.
Bugun bir muzeyga borsak.
What about us going to a museum today?
If the indicative present-future is used instead, the meaning is closer to making a decision than to expressing a wish.
Men ham. Kel, hozir sartaroshxonaga boramiz.
I want to have a haircut.
So I am. Come, let's go to the hairdresser.
With the interrogative, the use of the optative signals the speaker's request for instruction from the addressee
as to whether to perform some action (volitive).
Shall I pour some tea for you?
Nima deb qo'yay?
What should I say?
Futbol o'yiniga boraylik-mi?.
Shall we go to the football match?
The conditional suffix -SA plus the interrogative may be also used for the volitive.
Ertaga yo'lga chiqsam?
Could I not leave tomorrow?
