Neliosainen

Neliosainen is a Finnish adjective meaning “divided into four parts” or “four-part.” It is formed from the word osa, meaning part, together with the suffix -inen, and is used in combination with a numeral to indicate the number of parts. The term functions as a descriptive label rather than a fixed genre, applicable wherever a work or structure is organized into four distinct sections.

In practice, neliosainen is commonly used across arts, media, and education. In music, a neliosainen composition refers to a work with four movements or sections. In literature or journalism, it can describe a four-part series or serialized piece released in four installments. In broadcasting or film, a neliosainen program or documentary denotes a four-episode format. The usage is neutral and emphasizes structure rather than stylistic classification.

Related Finnish terms include kaksiosainen (two-part) and kolmisosainen (three-part). The English equivalent is “four-part.” Neliosainen can be inflected to fit grammatical context, such as neliosaisen teoksen or neliosaisen sarjan, depending on the sentence.
