Questions & Answers about Нет, я еду на метро.
Why use еду here instead of иду?
The verb еду comes from ехать, which means to go by transport. The verb идти (иду) means to go on foot. Because the person is traveling by subway, they must use the vehicle verb.
Why do we use the preposition на before метро?
In English, we say we travel by a certain transport, but Russian uses на (on) for modes of transportation. So, на метро literally translates as on the subway.
Doesn't the preposition на usually make the noun change its ending? Why is it just метро?
Yes, using на for transport requires the Prepositional case, which usually gives a noun an -е ending. However, метро is a borrowed foreign word. In Russian, many borrowed words ending in -о, -е, or -и (like кафе or такси) are indeclinable, meaning they never change their endings.
What is the dictionary form (infinitive) of еду?
The infinitive is ехать (to go by transport). It is irregular, so the stem changes in the present tense: я еду, ты едешь, он/она едет, and so on. You just have to memorize these forms.
