In Lithuanian grammar, nouns are categorized either as proper or common nouns. This distinction is crucial in the language. Proper nouns (vardinis daiktavardis) stand for unique entities like personal names, cities, countries and brands. They usually begin with a capital letter. On the other hand, common nouns (bendrinis daiktavardis) refer to general things, ideas or classes of things like cat, tree, and music. They are usually written in lowercase unless at the beginning of a sentence. This exercise will test your knowledge on how to distinguish and use them effectively in Lithuanian sentences.
