syntetisistä

Syntetisistä is a Finnish word form that functions as the elative plural of the adjective syntetinen, meaning synthetic or man-made. In Finnish, adjectives agree with the noun they modify in number and case, so syntetinen becomes syntetisistä when describing a plural noun in the elative case. The elative case is commonly used to indicate origin or source, often translated as “from” or “of.”

In practical use, syntetisistä appears most often in technical or descriptive texts. For example, syntetisistä materiaaleista means “from synthetic materials,” and syntetisistä kuiduista means “from synthetic fibers.” In noun phrases, both the adjective and the noun take the elative plural ending, as in syntetisistä materiaaleista valmistetut tekstiilit, meaning “textiles made from synthetic materials.” The form helps specify that the discussion concerns sources or origins related to multiple items.

Relation to other forms is straightforward: syntetinen is the base adjective meaning synthetic; other inflected forms exist for different cases, numbers, and genders of the noun they modify. The term is widely used in science, industry, and everyday descriptions of artificial or man-made substances and products.

Etymology traces syntetinen and syntetisistä to the international vocabulary for chemistry and materials science, rooted in the verb synthesize. The Finnish form reflects standard patterns of adjective inflection in the language.
