Tiedoihin

Tiedoihin is the illative plural form of the Finnish noun tieto, meaning information or knowledge. It is used to express movement toward or into information, or to indicate that statements are based on information or data. The illative plural suffix -iin is typical for nouns ending in -o, so tieto becomes tietoihin in this form.

In practice, tietoihin appears mainly in formal or written Finnish, especially in academic, scientific, or data‑driven contexts. For example, päätelmät perustuvat tietoihin translates to “the conclusions are based on information/data,” signaling reliance on multiple pieces of information. The form therefore often functions as a complement in sentences that discuss data sources, datasets, or information as a basis for reasoning.

Tiedoihin is not a standalone concept; it is a grammatical inflection of tieto. It should be distinguished from other related forms such as tietoon (singular illative, “into information”) or tiedot (plural noun meaning “pieces of information” or “data”). The illative plural emphasizes direction toward information and is commonly used when contrasting information with other sources or when describing data‑driven arguments.

In summary, tie- doihin serves as a grammatical tool in Finnish to refer to information or data in a directional sense, typically within formal discourse about research, analysis, or data interpretation.
