The Progressive Theory, also known as the Aspect Theory, is an important aspect of Slovak Grammar. It refers to the expression of ongoing actions or activities in the present or past. In Slovak, the progressive aspect is constructed by using the verb “byť” (to be) as an auxiliary verb in the present or past tense, followed by the present participle form of the main verb.

For example, to say “I am reading a book” in Slovak, we would say “Ja som práve čítajúci knihu,” where “som” is the present tense form of “byť” and “čítajúci” is the present participle form of “čítať” (to read). Similarly, to express past ongoing actions, we would use the past tense form of “byť” followed by the past participle form of the main verb.

The Progressive Theory is particularly useful in conveying a sense of duration or ongoingness in actions and activities. It allows us to differentiate between simple and ongoing actions, providing a more detailed description of events.
