datoissa

Datoissa is a Finnish term formed as the inessive plural of the borrowed noun data, meaning “in the data.” It is used to refer to information, findings, or content that reside within datasets or data records.

Etymology and grammar: The word comes from English data, which in Finnish is treated as a foreign noun with various inflectional patterns. In Finnish, the genitive singular is datan, the inessive singular is datassa, and the inessive plural is datoissa. There are related forms such as datoja (partitive plural) and other case forms. In practice, datoissa appears in contexts describing what is found or implied within datasets, often in scientific or data-analytic writing.

Usage and nuance: In statistics, data science, and research reporting, datoissa is used to discuss results, patterns, or constraints that are observed within the data. For example, one might say that certain correlations are evident datoissa or that limitations are visible datoissa. Some speakers treat data as a mass noun and may prefer datassa (singular) or use other expressions like tiedot to avoid ambiguity. Style guides in Finnish sometimes recommend aligning plural or singular usage with the overall treatment of data as countable items versus a collective resource.
