Questions & Answers about На этом уроке мы не будем писать, а будем читать вслух.
With урок, Russian usually uses на when talking about something happening during a lesson/class.
- на уроке = in class / during the lesson
- на этом уроке = in this lesson / during this class
Using в этом уроке would more likely suggest inside the lesson as a unit of content, for example inside a textbook lesson, not the normal idea of what happens in class.
So here на этом уроке means during this lesson.
This is the prepositional case.
The preposition на often takes the prepositional case when it means on / at / in a location or setting.
So:
- этот урок = this lesson
- на этом уроке = in/during this lesson
Both words change:
- этот → этом
- урок → уроке
This is the normal masculine singular prepositional pattern.
