In this exercise, you will practice using “Nomes contáveis e incontáveis” in Portuguese grammar. Countable nouns (Nomes contáveis) are nouns that can be counted, such as books, cars, and chairs. Uncountable nouns (Nomes incontáveis) are nouns that cannot be counted, such as water, air, and happiness. These nouns impact the way we use articles, quantifiers, and verbs in a sentence. The exercises will help you recognize and use countable and uncountable nouns in Portuguese.
