In Lithuanian grammar, the Tense Comparison Theory refers to the concept of comparing different tenses and their meanings. Tenses in Lithuanian can be divided into past, present, and future, each with their own specific forms.

The past tense is used to talk about actions or events that occurred in the past. It has several forms, such as the simple past tense, the past continuous tense, and the past perfect tense. These forms allow for greater precision in expressing different aspects of past actions.

The present tense is used to talk about actions or events that are happening at the present moment or are ongoing. It is a versatile tense that can be used in various contexts, such as describing habits, stating general truths, or expressing current actions.

The future tense is used to talk about actions or events that will happen in the future. It can express intentions, plans, or predictions. Like the past and present tenses, the future tense also has different forms that allow for different shades of meaning.

By studying the different forms and meanings of tenses in Lithuanian grammar, learners can better understand how to express themselves accurately and effectively in the language.
