prognoosidel

Prognoosidel is an Estonian grammatical form that functions as the adessive plural of the noun prognoos, meaning forecasts or predictions. In usage, prognoosidel translates roughly to “on forecasts” or “based on forecasts,” indicating a basis or context supplied by multiple forecasts.

Etymology and meaning: prognoos is a loanword in Estonian, commonly traced to the German word Prognose and ultimately linked to broader European linguistic sources such as Latin and Greek through historical contacts. The plural forms follow standard Estonian declension patterns: prognooside (genitive plural), prognoose (partitive plural), and prognoosidel (adessive plural). The adessive form is used to express location or reference relative to the forecasts, for example: Prognoosidel põhinevad otsused (Decisions based on forecasts).

Usage and domains: the term appears in journalism, economics, meteorology, and risk assessment to discuss how decisions or analyses rely on forecasts. It can describe methods, plans, or frameworks that incorporate multiple forecast sources, or indicate the source of information for a given argument. While widely used in formal and technical writing, its meaning remains tied to the general concept of prediction rather than to a specific field.

Related terms: prognoos (singular), prognoosid (nominative plural), prognooside (genitive plural), prognooside põhinevad (based on forecasts). The article of forecast in Estonian shares cognates with the broader concept of prognosis found in many languages.
