melléknévjelleg
Melléknévjelleg, also known as adjective declension, is a grammatical category in Hungarian that indicates the grammatical case of an adjective when it modifies a noun. In Hungarian, adjectives must agree with the noun they describe in terms of case, number, and definiteness. The adjective's form changes to match the noun's case, which can be nominative, accusative, dative, or instrumental. For example, the adjective "piros" (red) changes to "piros" (nominative), "pirost" (accusative), "pirosnak" (dative), and "pirossal" (instrumental) to match the noun's case. This agreement is crucial for maintaining grammatical correctness in Hungarian sentences. The adjective's form also changes based on whether the noun is definite or indefinite, with definite nouns typically requiring a different form of the adjective. For instance, "a piros ház" (the red house) uses a different form of "piros" compared to "egy piros ház" (a red house). Understanding melléknévjelleg is essential for Hungarian learners to construct grammatically accurate sentences.
