Teost

Teost is the partitive singular form of the Estonian noun teos, which means a work, composition, or artwork. The word teos refers to a single work, such as a literary work, musical composition, or other creative or scholarly production. Teost, as a grammatical form, appears in contexts where the partitive case is required.

In Estonian, teos declines as follows in the singular: nominative teos, genitive teose, and partitive teost. In the plural it forms as teosed (nominative), teoste (genitive), and teoseid (partitive). The exact usage of these forms depends on syntactic function and the surrounding grammatical structures, particularly with verbs that govern the object in a partitive sense or with numerals and constructions that require the partitive.

Teost is commonly used in sentences that demand the partitive case, including negation or indefiniteness, where the speaker refers to “a work” in a non-specific or partial sense. It also appears after numerals or other qualifiers that align with the partitive usage of Estonian grammar. While teos is the base meaning “a work,” teost is one of its inflected forms and does not represent a separate lexical concept.
