Declensions in Lithuanian grammar are a rich and intricate part of learning the language. Much like in Latin, declensions change the form of the word to indicate its role in the sentence, modifying nouns, pronouns, and adjectives in terms of case, number, and gender. Lithuanian grammar has seven cases: nominative, genitive, dative, accusative, instrumental, locative and vocative, each with their specific uses. Understanding and applying these cases correctly is a core part of fluency in Lithuanian.
