Sisäpuolesta

Sisäpuolesta is the elative singular form of the Finnish noun sisäpuoli, meaning the inner side. The phrase translates roughly as “from the inner side” and is used to indicate origin, source, or starting point located inside something. The elative suffix -sta/-stä marks movement from or reference to the interior, so sisäpuolesta literally means “from the inner side.”

Use and meaning: The term appears in technical, architectural, medical, and descriptive Finnish when detailing internal surfaces, cavities, or internal aspects of objects and structures. It denotes a point of origin or extraction from within, rather than simply a location inside. It contrasts with forms that describe where something is located (such as inside or on the inner surface) rather than where it comes from. In practice, sisäpuolesta is often paired with other words to specify inner versus outer sides (for example, inner versus outer components).

Etymology and related forms: Sisäpuolesta is formed from the compound sisäpuoli (“inner side”) plus the elative case suffix -sta/-stä. Related terms include sisäpuoli (the inner side) and ulkopuoli (the outer side), with corresponding case forms to express internal versus external reference.

Notes: The term is most common in written or technical Finnish. In everyday language, speakers may use broader expressions such as “from the inside” to convey a similar idea, depending on context.
