Kohortu

Kohortu is a term that appears in Estonian language contexts as an inflected form of kohort, meaning cohort in English. The base noun kohort denotes a group of people defined for a statistical or research purpose, and kohortu is used within dependent phrases to express possession or attributes of that group. The borrowing history traces to the broader family of words associated with scientific vocabulary in Estonian, with cognates in other European languages such as German kohorte and English cohort.

In epidemiology and demography, kohort-based research studies involve tracking a defined kohort over time to observe outcomes, incidence, and risk factors. The term kohortu can occur in compound expressions such as kohortu suurus (cohort size), kohortu kirjeldus (cohort description), or kohortu uuring (cohort study). Because Estonian uses rich inflection, the word appears in various grammatical cases depending on syntax.

Outside scientific language, kohortu is rarely used as a proper noun. There is no widely recognized place name or personal name by that exact form in major reference works. If encountered as a proper noun, it is likely to be a niche or fictional designation rather than a standard geographic or genealogical name. In practice, Kohortu is best understood as a linguistic variant tied to the standard term kohort, rather than as a distinct, independently defined concept.
