"The boy is going to school."
Translation:Мальчик идёт в школу.
Does the accusative case ending trump the prepositional case? As wouldn't школу otherwise be школе when combined with в?
В/на are used with Prepositional when they mean place of action of where something is.
В/на are used with Accusative when they mean the direction of motion or action.
Ha ! I had the same question in an other topic ! Thank you for the clarification... I should have paid more attention to words in bold from the "Prepositional case" lesson ! :)
