Questions & Answers about Книга содержит полезные слова.
What does each word in the sentence mean?
Книга means book. Содержит is the third-person singular form of содержать, which means to contain. Полезные слова translates as useful words.
Why is the adjective полезные in that particular form, and how does it agree with слова?
In Russian, adjectives must agree with their nouns in gender, number, and case. Here, слова is the plural form of слово and functions as the direct object (accusative case) of the verb. Because inanimate nouns have identical nominative and accusative forms in the plural, полезные appears in its standard plural form to match слова.
Why is the verb содержит used in its current form?
The verb содержит is in the third-person singular present tense form of содержать. It agrees with the subject Книга, which is singular. This subject–verb agreement is a fundamental aspect of Russian grammar.
