Teostanud

Teostanud is an Estonian active past participle formed from the verb teostama, meaning to realize, implement or carry out. It is used to describe someone or something that has carried out an action or completed a task, and it typically functions as an attributive modifier or appears in predicate constructions.

In use, teostanud expresses that the subject performed the action. It occurs in noun phrases such as projekti teostanud meeskond (the team that carried out the project) and in sentences like Ta on teostanud oma plaani (He has carried out his plan). The participle conveys a sense of completed action with agency, distinguishing it from the passive form teostatud, which simply indicates that something has been realized.

Relation to related forms: teostatud is the passive past participle meaning “realized” or “completed,” whereas teostanud emphasizes the agent performing the realization. Both forms derive from teostama, with teostus serving as the nominalized sense of realization or execution.

Etymology and related terms: teostama is related to teos (work) and denotes bringing a plan or idea into reality. The noun teostus refers to realization or execution as a concept, while teostatud and teostanud are the participial derivatives used in different syntactic roles.
