omastavsõnaga

Omastav sõna, often translated as genitive case, is a grammatical case found in several languages, most notably in Estonian. It functions to indicate possession, origin, or relationship between nouns. In Estonian, the genitive case is typically formed by adding a specific ending to the noun. For example, the nominative singular word "maja" (house) becomes "maja" in the genitive singular when it functions as a possessive modifier for another noun, such as "maja katus" (the roof of the house). However, in many contexts, the genitive singular form of nouns ending in a vowel changes, for instance, "raamat" (book) becomes "raamatu" in the genitive singular.

The genitive case is crucial for expressing relationships such as ownership, part-whole relationships, and origin. It answers questions like "whose?" or "of what?". Beyond simple possession, the genitive case in Estonian can also denote the object of certain verbs or prepositions. For example, it can indicate the subject of an infinitive construction or the recipient of an action in specific grammatical structures. Understanding and correctly applying the genitive case is fundamental to constructing grammatically sound sentences in Estonian and similar languages. The formation of the genitive case can vary depending on the declension of the noun, making it a complex but essential aspect of the language's grammar.
