Ennustettaessa

Ennustettaessa is a Finnish adverbial participle derived from the verb ennustaa, meaning to forecast or predict. It is used to introduce a subordinate clause that describes the circumstances or time under which the main clause takes place. The form expresses simultaneity or conditionality related to the act of forecasting and is commonly found in formal or technical prose.

Formation and grammar notes. The word is formed as a passive present participle with the suffix -ttaessa, which yields a clause meaning “when being forecasted” or “in forecasting.” As a passive participial form, ennustettaessa does not assign an explicit agent to the action; the subject of anticipation or forecasting is typically left unspecified or implied. This construction allows writers to present observations or results in a concise, compact way without repeating the subject.

Usage and function. Ennustettaessa functions as an adverbial modifier indicating temporality or circumstance. It is most common in written Finnish, including scientific, statistical, or legal styles, where precise clause structure is valued. The form helps to link a background condition to the main clause, for example in discussions of forecast-related uncertainty, methodology, or outcomes that depend on predictive assumptions.

Related forms and contrasts. Ennustettaessa is one of several -ttaessa forms used to express time, condition, or manner in passive voice, such as laitettaessa (when being placed) or korjattaessa (while being repaired). These forms share a similar function: to situate the main clause within the context of an ongoing or hypothetical action.
