ilmoittaessaan

Ilmoittaessaan is a Finnish grammatical form. It is the instructive case of the third infinitive of the verb ilmoittaa, which means "to inform," "to announce," or "to report." The instructive case, also known as the third infinitive, is used to express a circumstance or manner in which an action is performed.

In the context of "ilmoittaessaan," it typically translates to phrases such as "when informing," "upon informing," "in informing," or "while informing." This form is used to connect two clauses, where the subject of both clauses is the same. The action described by "ilmoittaessaan" happens concurrently with or immediately precedes the action in the main clause.

For example, in the sentence "Hän poistui huoneesta ilmoittaessaan lähtevänsä," the verb "poistui" (he/she left) is in the past tense, and "ilmoittaessaan" describes the action of informing that happened at the same time or just before leaving. The sentence translates to "He/She left the room, informing that he/she was leaving."

The structure involves the verb stem plus the infinitive suffix "-ess-" followed by the case ending for the instructive, which is "-aan" for this particular verb. It is a common and flexible grammatical construction in Finnish for describing simultaneous or preceding actions by the same subject. Understanding this form is crucial for comprehending complex Finnish sentences and expressing nuanced temporal relationships between actions.
