Linjoihin

Linjoihin is the illative plural form of the Finnish noun linja, which can mean a line, a route or a policy/approach. In its illative form, linjoihin expresses movement into or inclusion within multiple lines or line-like groupings. The form is used with verbs that govern illative case, such as kuulua (to belong to) or liittyä (to relate to), as in sentences that describe membership or association with a set of lines.

Etymology and morphology: Linja is a common Finnish word with several senses, including physical lines, transportation routes, and abstract lines or guidelines. The illative plural suffix -iin denotes “into the lines” and is applied after the plural stem linjo- plus the common illative ending. This yields linjoihin, indicating movement toward or inclusion in several lines.

Usage: In transportation and infrastructure, linjoihin is used to refer to a group of bus, rail, or other transit lines. For example, Kaupungin linjoihin kuuluvat bussireitit 3, 7 ja 12 means “The city’s lines include bus routes 3, 7, and 12.” In organizational or planning contexts, linjoihin can denote lines of policy, strategy, or planning categories, as in käsitellään linjoihin liittyviä periaatteita (“principles related to the lines”). The term is primarily a grammatical tool rather than a concept with a fixed, standalone meaning.
