kohorttiin

Kohorttiin is the illative singular form of the Finnish noun kohortti, meaning a cohort or group of people or units that share a common characteristic or time period. The form is used to express movement into or inclusion in a cohort, for example when participants are assigned to a specific cohort in a study or program.

Etymology and usage context: Kohortti is a loanword in Finnish, derived from the concept of a cohort found in several European languages. The term ultimately traces back to Latin cohors, via Swedish or English usage. In Finnish science and social research, kohortti is common in contexts such as epidemiology, demography, education research, and military history, where researchers organize subjects into distinct cohorts for comparison or longitudinal observation. The illative form kohorttiin specifically signals “into a cohort” in sentences describing assignment, introduction, or enrollment.

Examples of use: Tutkimuksessa osallistujat jaettiin kahdeksaan kohorttiin. Henkilöt siirtyivät kohorttiin B tammikuussa. These sentences illustrate how kohorttiin marks the target cohort in processes of grouping or enrollment. Other related forms include kohortista (from the cohort) and kohorttiin osallistuvat (those entering the cohort).

Related terms and concepts: In research methods, the term kohorttitutkimus (cohort study) is a common designation for studies that follow a defined group over time. The concept of a cohort also appears in demographic and educational planning, where groups are tracked to analyze outcomes or changes.

In summary, kohorttiin is a grammatical form used to denote entering or joining a cohort, a foundational term in Finnish discussions of grouped or longitudinal study populations.
