also called: future tense of probability, potential or necessitive mode.
Present-future assumptive expresses that the state, event or action will likely occur or is likely occurring,
the knowledge of it being grounded on previous knowledge or on deduction.
Most of the time, the assumption is made on a future fact:
Havo bulutli. Yomg'ir yog'sa kerak.
The weather is overcast. It may rain soon.
Yeyishni istamasam kerak.
I may not want to eat.
I will probably not marry.
The assumption can also be made on a present fact:
U kishi o'zbek bo'lsa kerak.
This man must be Uzbek.
To emphasize that the action will probably occur, either balki or ehtimol, ('perhaps', 'probably'),
may be used in addition to the assumptive form.
Ehtimol, u ham kelsa kerak.
It is possible that he will come.
