Adjectives play a crucial role in the Lithuanian language, as they are an essential part of sentence structure and provide important information about the nouns they modify. In Lithuanian grammar, adjectives are categorized according to their endings, which can be either masculine, feminine, or neuter.

Adjectives in Lithuanian are also declined based on the case, number, and gender of the noun they describe. With 7 cases and 3 genders, this can result in a wide variety of possible adjective forms. Moreover, adjectives also change depending on whether they are used in positive, comparative, or superlative forms.

Furthermore, adjectives in Lithuanian also agree in gender, number, and case with the noun they modify, making the language highly inflected. This agreement is an important aspect of Lithuanian grammar, ensuring that the adjective matches the noun in all its grammatical features.

In summary, the study of adjectives in Lithuanian grammar involves understanding their endings, declensions, and agreement with nouns. A thorough understanding of these rules is essential for mastering the language and constructing grammatically correct sentences.
