Progressive Theory, also known as the form of “Imekõneviis” in Estonian Grammar, refers to the use of progressive verb forms to express ongoing actions or states in the present. In Estonian, this form is constructed by combining the verb “olema” (to be) in its present tense form with the adverb “parajasti” (currently) and the infinitive form of the main verb.

For example, the sentence “Ma olen parajasti õppimas” translates to “I am currently studying.” Here, the verb “õppima” (to study) is in its infinitive form, and combined with “olema” and “parajasti” to create the progressive form.

This construction is commonly used to express actions or events that are happening at the current moment. It can also imply a temporary state or ongoing activity. However, it is important to note that the progressive form is not as commonly used in Estonian as in some other languages, such as English. In many cases, the simple present tense is used instead to express ongoing actions or states.
