Sarjoihin

Sarjoihin is the illative plural form of the Finnish noun sarja, meaning series or serial. It is used to express movement toward or inclusion in multiple series, or to indicate that something belongs to more than one series. As a grammatical form, sarjoihin appears in contexts where the target or destination is a series in the plural.

In everyday Finnish, sarjoihin is most common when talking about media, literature, or other collections that are organized as series. It can describe items that are part of several linked works, as well as actions directed toward series, such as distributing or categorizing items into series. The word typically combines with verbs that govern the illative case, for example kuuluvat sarjoihin (belong to series) or julkaistut osat useisiin sarjoihin (new installments published in several series).

Because sarja covers TV series, book series, and other sequential works, sarjoihin often appears in discussions about publishing, broadcasting, and media franchises. The term helps distinguish whether items are standalone or part of a broader sequence, and it supports distinctions among multiple ongoing series in a given domain.

Examples:

- Nämä teokset kuuluvat sarjoihin. (These works belong to series.)

- Kustantaja on julkaissut uusia osia useisiin sarjoihin. (The publisher has released new installments in several series.)

Overall, sarjoihin is a practical and frequently used form in Finnish to reference membership in or direction toward multiple series within cultural, media, and publishing contexts.
