Imperfective inferential

Imperfective inferential is used for states, events or actions occurring habitually or repetitively, or happening during the period of reference, and expresses that the knowledge of the fact is inferred from evidence, be it sensorial perception, logical deduction or direct report from a trusted source. That knowledge is most often presented as new information, sometimes unexpected, for the speaker himself.
The temporal distinction between a past and a present state, event or action is not marked grammatically, the tense must be decided from the context.

● The knowledge might be inferred from sensorial perception:

O'zbekcha tushunar ekan.
Hey, he does understand Uzbek.

● The knowledge might be inferred from logical deduction:

Ertaga kelar ekanman.
It appears that I will come tomorrow.

● The knowledge might be obtained from a direct report from a trusted source:

Ota-onasi qayerda ishlar ekan?
Where are working his parents?

● The state, event or action may have occurred in the past:

Ular yo'lda ketar ekan, turli qushlarning ovozi eshitilib turmoqda edi.
While they were going their way, the voices of all sorts of birds were heard.

● Or it will occur in the future:

Kechasi sen unga telefon qilmas ekansan, chunki u uyda bo'lmas ekan.
(It seems that) you won't phone him at night, because he won't be at home.
