Tenses play a crucial role in Latvian grammar as they indicate the time of an action or event in relation to the present, past, or future. In Latvian, there are three main tenses: present, past, and future.

The present tense is used to describe actions or events happening in the current moment. It is formed by adding specific endings to the verb stem. The past tense, on the other hand, is used to talk about actions or events that have already happened in the past. It is formed by adding different endings to the verb stem.

The future tense is used to express actions or events that will happen in the future. In Latvian, the future tense is formed by adding specific endings to the verb stem, similarly to the present tense.

Additionally, Latvian grammar also includes other tenses such as the present perfect, past perfect, and future perfect tense. These tenses are used to talk about actions or events that have been completed or will be completed in the past, present, or future respectively.

Understanding the concept and usage of tenses is essential in mastering the Latvian language as it allows for accurate communication of time-related information.
