Learn Polish: Według rozkładu jazdy autobus już odjechał od przystanku. - According to the timetable, the bus has already driven away from the stop.

When a motion verb has the prefix od- (meaning departure or separation), it is very often paired with the preposition od (from) to show what the subject is moving away from. Together, odjechał od means "drove away from". The preposition od always requires the Genitive case.

Could I use wyjechał instead of odjechał to say the bus departed?

Generally, no. The prefix wy- means moving out of an enclosed space (like a garage, a city, or a country). A bus stop (przystanek) is just an open location on the street. Because the bus is simply moving away from that point, the prefix od- is the right choice.

Why is the word for "bus stop" spelled przystanku here?

It follows the preposition od, which requires the Genitive case. The base word is przystanek (a masculine noun). When forming the Genitive, the last -e- disappears (a common pattern called a "fleeting e") and we add the masculine Genitive ending -u, making it przystanku.
