tieteellistä

Tieteellistä is the partitive singular form of the Finnish adjective tieteellinen, meaning scientific or pertaining to science. In Finnish, adjectives decline to agree with the noun they modify, and tieteellistä is used when the modified noun is in the partitive case or refers to an indefinite amount or non-count noun.

Common usage occurs in scientific and academic contexts. For example, tieteellistä tietoa means scientific information, tieteellistä tutkimusta means scientific research, and tieteellistä näyttöä means scientific evidence. In plural forms the corresponding partitive is tieteellisiä, as in tieteellisiä tutkimuksia (scientific studies). The form tieteellistä thus functions as a grammatical tool to express indefiniteness or non-counting of the noun it describes.

Etymologically, tieteellinen is formed from the noun tiede, meaning science or knowledge, with the suffix -ellinen that creates adjectives meaning “pertaining to” or “characteristic of.” The word is widely used in everyday Finnish when discussing science, research results, or evidence, and it also appears in media, education, and policy discourse to specify content or claims as scientifically grounded.

Related terms include tiede (science), tieteellisyys (scientificity or the quality of being scientific), and tieteellisesti (adverbial form meaning scientifically). While tieteellistä is the partitive singular form, other inflections align with the noun they modify, allowing precise grammatical expression of quantity and case in Finnish.
