Commitment is the result of a decision which has been explicitly spoken out and made known to the outer world, so that the speaker is bound by his or her decision. It expresses notions such as: 'will definitely', 'promise to'.
It is related to mood, since there is an effect of the utterance on its listener.

● The adverbial albatta ('definitely', 'certainly', 'naturally'), is the main device to express commitment.

Ertaga kelasizmi?
Albatta kelaman.

Will you come tomorrow?
Yes, certainly.

Modomiki shu ishni qilishimiz kerak ekan, albatta, qilamiz.
As we have to do this work, we will do it without fail.

Albatta, siz meni hech qachon rozi bo'lmaydi deb o'ylayapsiz!
You can imagine I would have never agreed!

- The adverb albatta takes on different shades of modality, from deontic obligation and commitment, down to epistemic modality of certainty and naturalness of the fact referred to in the sentence.

Albatta yo'q!
Definitively no!

Albatta roziman.

Will you accept?
Of course I will!

Ha, albatta.
Yes, of course!

Bu albatta mumkin.
It's perfectly possible.

● Another construction expressing commitment is:
- "verb-ISHGA VA'DA BER-", based on the compound verb va'da ber-, 'to promise'.

U qo'shnisiga yordam berishga va'da berdi.
He promised his neighbour to help him.

U o'ziga o'zi boshqa qaytarmaslikka va'da berdi.
He promised to himself not to do it again.
