aikataulusta

Aikataulusta is the genitive singular form of aikataulu, formed with the suffix -sta. Aikataulu means timetable or schedule, such as a train timetable or an event schedule. In Finnish, the -sta/-stä ending is used to express origin or source, and it is also used with certain verbs to indicate the topic of discussion. Therefore aikataulusta can mean “from the timetable” or “about the timetable,” depending on the context.

Usage of aikataulusta commonly arises when the timetable is the subject of conversation, inquiry, or reference. It is frequently found in journalism, transportation notices, and planning documents where the timetable is discussed or cited. While other forms of aikataulu exist to denote possession or location—such as aikataulun (genitive) or aikataulussa (in the timetable)—aikataulusta is chosen to convey that the timetable is the topic or source being referred to.

Examples include: Keskustelimme aikataulusta. (We discussed the timetable.) Hän kirjoitti aikataulusta artikkelin. (He wrote an article about the timetable.) Aikataulusta voi löytää tietoja reiteistä ja aikatauluista. (From the timetable one can find information about routes and schedules.) These usages illustrate how aikataulusta functions as a topic- or source-marking form in Finnish discourse.
