Objective possibility and permission

Objective possibility refers to the possibility an agent has to perform an action, or that a situation occurs, due to objective external factors.
Permission refers to the possibility an agent has to perform an action, thanks to an external authority.
Both possibilities may be more or less normative, that is the external enabling factor may be more or less general and abstract, or conversely, personal and concrete. For instance general factors vs specific circumstances, or human law vs. persons.

● The nominal construction "verb-ISHI MUMKIN", i.e. the infinitive suffixed with the possessive type of personal suffix, and followed by the nominal predicate mumkin ('possible'), is the main form used to express objective possibility as well as permission.
To express a possibility which applies to anybody or anything, the personal suffix is not used.

- Objective possibility, of general application:

Bu magazinda qog'oz topish mumkinmi?
Can paper be found in this store?

Maydonda yana bitta haykalni ko'rish mumkin.
You can see still another statue on the place.

Mumkin bo'lsa, kelarsiz.
If it is possible, please come.

- Objective possibility, for a specific person or fact:

Qizim, boshliqni qayerdan topishim mumkin?
Where can I find the boss?

Mana bu so'zni tushunmadim, uni qanday tarjima qilishim mumkin?
I didn't understand this word, how could I translate it?

Buning bo'lishi mumkin emas.
It is not possible.

Biz bilan yuz berishi mumkin bo'lgan baxtsizliklar.
Misfortunes which can happen to us.

- Performative modality: Permission:

Men ham borishim mumkinmi?
Could I also enter?

Kirish mumkin.
You can come in.

Sizdan so'rashim mumkinmi?
Can I ask you?

O'quvchilar chiqishlari mumkin.
The pupils can go out.

- The possessive pronoun may be used for emphasis.

Uning chekishi mumkin emas.
He cannot smoke.

- That construction, especially at the past form (using the past stative edi), may carry an epistemic meaning, meaning the fact mentioned in the sentence may probably happen. The probability of occurrence is then somewhat intermediate between the assumptive form in "-SA KERAK" and the presumptive form in -AR.

Xuddi shunday bo'lishi mumkin edi.
It could be well possible.

Unga bu nima ham qila olishi mumkin edi?
Would he possibly matter for that?

● The verbal construction "verb-SA BO'L-", i.e. the conditional (suffixed with the possessive type of personal suffix), followed by the verb bo'l- ('to be', 'to become') conjugated at the (impersonal) singular third person, expresses an objective possibility as well as permission, with the additional shade of more normativity, the external enabling factor being a more general and abstract law, and not mere circumstances or individuals.
The same range of meanings may be also expressed by the much rarer nominal construction "verb-SA MUMKIN".

- Objective possibility, as a result of a general rule, and of general application:

Kasalxonaga qanday borsa bo'ladi?
How to go to the hospital?

- In this meaning, the construction "verb-IB BO'L-", i.e. the past gerund followed by the verb bo'l- conjugated at the (impersonal) singular third person, can also be used, especially at the negative form, implying the impossibility to do, or the necessity not to do.

Yerni haydasa/haydab bo'ladi.
The soil can be ploughed.

Bu o'rinda hech narsa qilib bo'lmaydi.
We can't do anything for that.

Qishloqlarda, paxta dalalarida ruslarni uchratib bo'lmaydi.
You won't meet any Russian in the villages or in the cotton fields.

- Also, at the stative, instead of using "bo'lsa bol'adi", or "bo'lib bo'ladi", the simple use of bo'l- can be enough to convey the meaning of objective possibility (or impossibility).

Bundan yaxshiroq bo'lmaydi.
Better than that is impossible.

- Performative modality: Permission (and interdiction):

Xonani ko'rsam bo'ladimi?
May I have a look at the room?

Kirsam mumkinmi?
May I come in?

Shu kitobni olsam mumkinmi?
Can I buy this book?

Bormasak bo'lmaydi.
We cannot not go.

- In this meaning of permission, the nominal construction "verb-SA MAYLI" can also be used.

Sizga yordam bersam maylimi?
May I help you?

- In some cases, the "verb-SA BO'L-" construction may take on a meaning implying internal ability more than objective possibility or permission.

Bu ishni bir kunda bajarsam bo'ladi.
I can finish that job in one day.
