Progressive theory is an essential aspect of Kazakh grammar that denotes ongoing actions or states in the present. It is used to emphasize the dynamic nature of an action or event. In the Kazakh language, the progressive form is formed by combining the verb “бол-” (to be) with the present participle of the verb.

For example, the sentence “Мен студентпен оқу жасаймын” (I am studying with my friend) can be transformed into “Мен студентпен оқып жатаймын” (I am currently studying with my friend). Here, the addition of the progressive form “жат-” indicates the ongoing nature of the action.

The progressive form is also used to express changes happening at the moment of speaking. For instance, “Ол кітап оқыған” (He read a book) can be transformed into “Ол кітап оқып жатпайды” (He is currently reading a book).

Overall, the progressive theory in Kazakh grammar plays a significant role in expressing ongoing actions and highlighting the dynamic nature of events in the present. It adds depth and context to the language, making conversations more descriptive and precise.
