Questions & Answers about Это полезная вещь.
What is the role of это in the sentence Это полезная вещь?
In this sentence, это functions as a demonstrative pronoun that introduces or identifies the subject. It’s used similarly to “this is” or “it is” in English, serving as a pointer to what is being described by the rest of the sentence.
Why is the adjective полезная in its particular form?
The adjective полезная ends with -ая because it must agree in gender, number, and case with the noun it describes, which is вещь. Since вещь is a feminine noun in the singular nominative case, the adjective takes its feminine singular form.
What case is the noun вещь in, and why is that important?
Вещь is in the nominative case, which is used for subjects and predicate nominatives in simple statements. In this sentence, it serves as the complement to это, meaning that it describes or identifies the subject, thus reinforcing the standard structure of equational sentences in Russian.
Is the word order in Это полезная вещь significant, and can it be changed?
The word order here is typical for Russian equational sentences, with это introducing the subject followed by the descriptive predicate (полезная вещь). While Russian allows for flexible word order to emphasize different parts of a sentence, this structure is the most natural and clear for expressing a simple, factual statement.
What does вещь mean, and are there any nuances to its usage?
Вещь generally translates to “thing” or “object” and is commonly used in everyday Russian. It is a neutral term that can refer to both concrete objects and abstract concepts, depending on context. In the sentence Это полезная вещь, it simply labels the item as a “useful thing” without additional connotations.
