sisällön

Sisällön is the genitive singular form of sisältö, a Finnish noun meaning content, substance, or subject matter—the information or material conveyed by a work, medium, or communication. It refers to what a text, site, video, or other artifact presents to an audience, as distinct from form, style, or presentation.

Etymology: sisältö is connected to the verb sisältää, meaning "to contain," reflecting its core sense of what something contains. The word is widely used in journalism, publishing, education, and information design.

Usage: The form sisältön is used to indicate possession or association, as in verkkosivun sisältö (the content of the webpage), raportin sisällön rakenne (the structure of the report’s content), or sisällön laatu (the quality of the content). The plural form is sisältöjen, used when referring to multiple contents or multiple items of content.

In professional contexts, sisältö is a central concept in content strategy, content creation, and content management. Discussions often distinguish content from form, layout, and user experience, focusing on accuracy, clarity, relevance, and accessibility.
