Questions & Answers about Метро в Москве быстрее, чем городской автобус.

How is the comparative form "быстрее" formed, and what does it indicate in this sentence?

"Быстрее" is the comparative form of the adjective быстрый (fast), meaning faster. In this sentence, it indicates that the metro has a higher speed than the city bus. The construction is similar to the English "faster than" where only the quality being compared is put into the comparative form.

What role does чем play in the sentence, and why is there a comma before it?

Чем functions as a conjunction meaning than, introducing the element being compared with the metro—in this case, the city bus. The comma before чем is a standard punctuation rule in Russian that separates the main clause from the comparative clause.

Why is the phrase в Москве written with Москве instead of Москва?

In Russian, when expressing location with the preposition в (in), the noun must be in the prepositional case. Москве is the prepositional form of Москва, so в Москве means in Moscow.

What does the term городской автобус mean, and why is the adjective городской used here?

Городской автобус translates to city bus. The adjective городской (urban or city) is used to specify that the bus in question is a type used for city transport rather than intercity or suburban travel.
