"A busz este indul."

Translation: The bus departs in the evening.

[O_Matty]

Should there be some kind of postposition on "este" to make it "in the evening"?

[jsiehler]

No, este and reggel (morning) can both function as time adverbs ("in the evening" and "in the morning") without any endings.

[Krisbaudi]

Depart was marked wrong, but I think it is right.

[jsiehler]

Yes, "The bus departs in the evening" is fine.

[Imre565437]

departs

[JereArmen]

Isn't "starts out" also an acceptable translation of "indul"? (It was rejected.)
