tähistuste

Tühistuste is the genitive plural form of the Estonian noun tühistus, which denotes cancellation, annulment, or voiding of a legal act, contract, agreement, or decision. It is used to refer to multiple cancellations or annulments and appears mainly in formal or technical contexts.

In usage, tühistuste is typically found in legal, administrative, and business texts to describe or quantify cancellations. For example, phrases like tühistuste mõju (the impact of cancellations) or tühistuste arv (the number of cancellations) illustrate how the term functions as a noun phrase modifier. The form is generated by adding the genitive plural ending -uste to the base tühistus, following Estonian grammar rules for -us nouns.

Contextually, tühistuste can relate to a wide range of cancelation activities, including the cancellation of contracts, permits, registrations, events, or official decisions. The concept is distinct from related verbs such as tühistama (to cancel or annul) and adjectives describing the cancellable nature of a thing, such as tühistatav.

Grammatical notes: tühistuste is used when the speaker or writer refers to cancellations in a broader sense or when counting and describing their aspects. It is common in reports, analyses, and regulatory documents where precise terminology distinguishes cancellations from other forms of change or reform.
