Vastag

Vastag is a Hungarian word that functions as an adjective meaning thick, dense, or heavy. It is used to describe physical dimensions and material properties, such as a vastag fal (thick wall), vastag jég (thick ice), a vastag réteg (thick layer), or a vastag krém (thick cream). The term can also describe viscosity or consistency, as in a very thick sauce. In addition, vastag can carry metaphorical senses to indicate abundance or intensity, though literal thickness is the most common usage.

In grammar, vastag agrees with the noun it describes in number and case. The comparative form is vastagabb and the superlative form is legvastagabb (thicker, thickest). For example, one might say that a wall is vastagabb than another, or that a zone contains legvastagabb köd (thickest fog), depending on context and noun.

Vastag is also a Hungarian surname. As a family name, it appears among Hungarian-speaking populations and in diaspora communities. While etymologically connected to the adjective, as a surname it functions independently of its descriptive sense.
