Sugárnak

Sugárnak is the dative singular form of the Hungarian noun sugár, meaning ray, beam, or ray of light. In Hungarian grammar, sugárnak marks the indirect object or the direction toward which an action is directed, following the rules of the dative case. The base noun sugár has several related senses: in optics, a beam or ray of light; in geometry, a half-line starting at a given point and extending indefinitely; in everyday language, a streak or jet of light or energy. The word is native to Hungarian, and the dative ending -nak is attached according to vowel harmony.

In usage, sugárnak appears when the sentence requires designation of the recipient or beneficiary of an action, or when describing direction toward which something is aimed. The plural dative form is formed by applying the standard plural suffix to the noun, which in practice yields a form such as sugaraknak in contexts referring to multiple rays.

Sugár is also the root of several related terms in science and everyday language. Sugárzás denotes radiation or emanation, while sugárkapcsolat or sugárút may appear in more specialized or compound words. Across contexts, the core meaning of sugár remains tied to a line or beam extending from a source, and sugárnak functions as the grammatical form that directs attention to the indirect object or target of an action.
