Factual conditional

In factual conditional, the condition clause expresses a condition whose truth is unspecified or unverified.
The most common use is to express a hypothetical condition that is potentially true, but not yet verified (potential conditional).
It can also be used to express a certainty or a universel statement (zero conditional, equivalent to 'when(ever)').

● The potential conditional makes use of the verbal construction "verbal form-SA", in the conditional clause, and of a declarative or imperative mood in the result clause.

- The most common use is with the verbal stem plus the suffix -SA in the condition, and the present-future in the result clause.
The condition refers to a future event (or state), a current event which may be true or untrue, or an event which could be verified in the future. The result is then in the future.

Agar universitetga kelsangiz, masalani birga yechamiz.
If you come to the University, we shall solve the problem together.

Ishlab, ozgina pul topsam, o'zimga ham, sizlarga ham yaxshi bo'ladi.
If I get some more money by working, it will be better for both you and me.

Bugun kelsangiz, bu kitobni darrov beraman.
If you come today, I will give you the book at once.

Siz kelmasangiz, biz teatrga bormaymiz.
If you don't come, we will not go to the theatre.

Siz agar uyingizdan chiqib ketib qolmasangiz men siznikiga boraman.
I will go to your place, unless you go out.

- With the focal present in the result clause, the condition refers to a current event or state.

Agar u shu yerda bo'lsa, kutubxonada ishlayapti.
If he is here, he is probably working in the library.

- The condition itself may be focalized in the present, if using the construction "verb-YOTGAN BO'LSA".

Agar ish yoqmayotgan bo'lsa, hasratingni ayt-ku.
If you don't like the job, express your grievance!

- The condition can refer to a past event, for a result which can be in the past, but also in the present or the future. It makes use of the construction "verb-GAN BO'LSA". This must not be confused with the counterfactual conditional, where the fact expressed by the proposition is false. Here it may still hold true, even if unverified.
For an exemple with a result in the past:

Agar u ularnikiga kecha kirgan bo'lsa, unga kitobni berishgan.
If he called on them yesterday they gave him the book.

- Various modalities can be expressed in the result clause, such as imperative, ability, presumptive.

Borasanmi? Agar borsang, meni oldindan ogohlantirib qo'y.
Will you go? If yes, please tell me in advance.

Yomg'ir yog'sa, biz stadionga bora olmaymiz.
If it rains, we will not be able to go to the stadium.

Agar u bo'lsa, menga aytarsan.
If it's him, you will tell me.

Toshkentda ish topsam, balki qolarman.
If I find a job in Tashkent, may be I would stay.

- Some modality can be also expressed in the condition clause, such as intention, uncertainty (presumptive) in the future:

Agar siz bu filmni ko'rmoqchi bo'lsangiz, kassetalarni Anvardan oling.
If you want to see this movie, borrow the tape from Anvar.

Yozar bo'lsam, ...
Should I write in the future, ...

● The conditional with the present-future in the result clause can also express a certainty or a universel statement, expressed in English by the adverbial 'when(ever)').

- That can express a general or universal value:

Qanday yaxshi, do'stlar bilan uy to'lsa.
It is so good when home is full of friends.

Bola yig'lamasa, ona sut bermaydi.
If a child does not cry, the mother does not suckle.

- In conjuction with adverbial ham ('also') or the final particle da, the conditional and result clauses express together concessive ('even if'):

Agar men unga aytsam ham, bu hech narsani o'zgartirmaydi.
Even if I tell him, that won't change anything.

Biz birga o'qigan bolsak ham, bir-birimizni yaxshi bilmaymiz.
Even if we have studied together, we don't really know each other.

Yozib tursang-da, ...
Even if you continue writing, ...
