tõestasid

Tõestasid is a verb form in Estonian. It represents the past tense of the verb tõestama, which means to prove, to demonstrate, or to attest. The form is used to indicate that someone proved or demonstrated something. In written language, tõestasid can function for both the second person singular and the third person plural, depending on context; the exact subject is usually clear from surrounding text.

Usage and context: Tõestasid appears in narrative reports, legal or academic writing, journalism, and everyday speech when recounting proved claims, evidence, or outcomes. Because it is a finite past tense form, the subject is implied or stated elsewhere in the sentence. It often accompanies objects such as väide (claim), tõendus (evidence), or tõendid (proofs), and signals that the asserted proposition was substantiated.

Related forms and related terms: The verb tõestama has other tense forms, including present and past singular and plural variations (for example, tõestan, tõestad, tõestab, tõestasin, tõendasid, tõestasime, tõestasite, tõestasid). The noun tõde or tõestus is connected etymologically, with tõestus meaning proof or verification. In Estonian, the root tõest- is linked to the concept of proving or certifying something as true.

Notes: Tõestasid is inherently context-dependent for voice and number, and its precise subject is determined by the surrounding sentence. The form is common in formal and informal Estonian alike, where stating that a claim was proved is necessary.
