Learn Hardcore Russian: Сегодня я опоздал в школу.

In Russian, adverbs of time such as Сегодня (“today”) are often positioned at the beginning to establish the context of when the action occurred. Although Russian word order is relatively flexible, starting with Сегодня emphasizes the time frame for the event.

What case is used for школу, and why is it in that case?

The noun школу is in the accusative case. In contexts where the preposition в indicates movement toward a destination, Russian requires the accusative form. This differs from situations that express location (e.g., в школе, meaning “at school”), which would use the prepositional case.

Why does the sentence use опоздал without an auxiliary verb like “was” as in English?

Russian constructs past tense statements without an equivalent to the English auxiliary “was.” The past tense is directly shown by the verb form itself. In this sentence, опоздал inherently indicates that the action happened in the past, so no additional copular verb is needed.

Why is опоздал in the masculine form, and how would it change for a female speaker?

Russian past tense verbs agree with the subject’s gender. Here, опоздал is the masculine singular form, appropriate if the speaker is male. If a female were speaking, the verb would change to опоздала to match her gender.
