In Ukrainian grammar, countable and uncountable nouns play a significant role. Countable nouns, also known as “лічильні іменники,” can be easily counted and have both singular and plural forms. On the other hand, uncountable nouns, or “нелічильні іменники,” refer to objects, substances, and ideas that cannot be counted and only have a singular form. Understanding the proper usage of countable and uncountable nouns in Ukrainian helps learners develop a strong foundation in the language, particularly when it comes to constructing grammatically accurate sentences.
