Learn Hardcore Russian: Пациент ждет врача. - The patient is waiting for the doctor.

The sentence follows a Subject + Verb + Object pattern. Пациент is the subject in the nominative case, ждет is the verb (third-person singular form of ждать in the present tense), and врача is the direct object.

Why does the object врача have an ending of -а even though it is the direct object?

In Russian, masculine animate nouns like врач take an accusative singular form that is identical to their genitive singular form. So, although врача looks like it could be genitive, it is functioning as the accusative object of the verb ждать.

Why isn’t there a preposition like "for" before врача as we see in English ("waiting for")?

The verb ждать already incorporates the meaning "to wait for," so no preposition is needed. The object directly follows the verb in its appropriate form (here, the accusative/animate form) without any additional word.

How does the verb ждет indicate information about the subject in the sentence?

Ждет is the third-person singular form of ждать, which tells us that the action is being performed by a single entity—пациент. Its conjugation reflects both the person (third person) and number (singular) of the subject.

Are there alternative verbs for "to wait" in Russian, and what nuances might they add?

Yes, another common verb is ожидать. While both ждать and ожидать mean "to wait," ожидать often implies an element of expecting something or someone and might sound slightly more formal. In everyday conversation, ждать is typically used, as seen in this sentence.
