Questions & Answers about Я учу друга читать книгу.
What is the overall structure of the sentence "Я учу друга читать книгу"?
The sentence consists of a main clause and an infinitive complement. In the main clause, "Я учу друга" identifies who is teaching (Я – "I") and who is being taught (друга – "friend" in the accusative case). The infinitive phrase "читать книгу" explains what the friend is being taught to do.
Why is "друга" in the accusative case?
In Russian, the verb "учить" (to teach) requires a direct object to indicate who is being taught. Since "друг" is an animate, masculine noun, its direct object form in the accusative singular is "друга."
What role does the infinitive "читать" play in this sentence?
The infinitive "читать" serves as a complement to "учить." It tells us which action is being taught—in this case, the skill of reading. Using an infinitive after verbs like "учить" is common in Russian to specify the activity or skill involved.
Why does the noun "книга" change to "книгу" in this sentence?
"Книга" is a feminine noun, and when it is used as the direct object of an action—in this case, in the infinitive phrase "читать книгу"—it must be put into the accusative form. For feminine nouns, this typically means changing the ending, so "книга" becomes "книгу."
Is the addition of the phrase "читать книгу" necessary after "Я учу друга"?
Yes, it is necessary for clarity. While "Я учу друга" indicates that teaching is happening, the infinitive phrase "читать книгу" specifies what is being taught. Without it, the sentence would leave the learner wondering which skill or activity is involved in the teaching.
Can the word order in this sentence be rearranged without changing its meaning?
Russian allows a flexible word order because of its case system, which clearly marks the roles of the words. However, the standard order "Я учу друга читать книгу" is preferred for clarity. Rearranging the elements might be done for emphasis, but care must be taken to retain the clear functions of the subject, direct object, and complement.
