Runkojen

Runkojen is the Finnish genitive plural form of the noun runko. In Finnish grammar the genitive plural marks possession, origin or a relationship involving multiple instances of the base noun; runkojen therefore conveys "of the frames", "of the trunks" or "of the cores" depending on context.

The base word runko has a range of meanings in Finnish, including frame, trunk, skeleton, hull or main body. It is used across disciplines: in engineering and construction to denote the structural frame of a building or vehicle; in biology to refer to the trunk of a plant or the body core of an organism; in furniture and product design for the primary support structure; and in computing to describe a framework or core architecture. Runkojen appears in compound phrases such as runkojen suunnittelu (design of the frames) and runkojen kestävyys (durability of the hulls/frames).

Usage depends on syntax and intended nuance: runkojen followed by another noun typically indicates a relationship between multiple frames and that noun, while adjectival or verbal contexts may require case agreement elsewhere in the sentence. As with other Finnish case forms, precise meaning is guided by context and collocation rather than a one-to-one translation.

Related terms include runko (the singular), rungot (plural nominative), and runkoon/runkoa in other cases; runkojen is specifically the genitive plural form used in possessive and relational constructions.
