teostasid

Teostasid is an Estonian verb form meaning “they realized” or “they carried out.” It is the past tense, third person plural form of the verb teostama, which means to realize, implement, or execute. Teostasid is used when the subject is a group that completed an action, such as a plan, project, decision, or instruction.

In usage, teostasid typically governs a direct object in the accusative or partitive case, indicating what was carried out. Examples: Nad teostasid oma plaani. (They carried out their plan.) Nad teostasid projekti töökalt. (They implemented the project successfully.) Nad teostasid lubadused. (They fulfilled their promises.)

The verb teostama belongs to the common Estonian class of verbs formed from a noun or concept related to “work” or “execution.” The past plural form teostasid contrasts with singular forms such as teostas (he/she realized) and teostasid (you plural realized) depending on the subject.

Usage notes: teostasid is more likely to appear in written or formal contexts, such as news reports, official statements, or academic writing, where completed actions by groups are described. In everyday speech, speakers may opt for synonyms like täitles, realiseerima, or to realize, depending on nuance.
