Tense theory in Slovak grammar is a complex concept that deals with the different forms and uses of verb tenses in the Slovak language. In Slovak grammar, verb tenses are classified into three main categories: past, present, and future.

The past tense is used to talk about completed actions or events that occurred before the present moment. It includes various forms such as the past simple, past continuous, and past perfect.

The present tense is used to talk about actions or events that are happening now or are generally true. It includes forms such as the present simple, present continuous, and present perfect.

The future tense is used to talk about actions or events that will happen in the future. It includes forms such as the future simple, future continuous, and future perfect.

Each tense in Slovak grammar has its own set of rules and conjugation patterns, which students must learn and practice. Understanding and correctly using verb tenses is crucial for effective communication in Slovak.
