felületbe

felületbe is the illative form of the Hungarian noun felület, meaning surface. In Hungarian grammar, the illative case marks direction into something or penetration into its interior, and felületbe is used when an action moves into a surface or into the interior of a surface. It is a postpositional inflection that accompanies inanimate, non-personal nouns such as surfaces, layers, or coatings, and it commonly appears in technical, scientific, or descriptive prose.

The form felületbe is created by adding the illative suffix -ba/-be to the noun felület; since felület ends with a consonant, the form takes -be. The illative indicates motion toward or into the surface, and it is often found with verbs that describe entering, piercing, drilling, or embedding actions. It contrasts with other illative forms of related nouns and with the corresponding inessive or elative forms, which express inside or out of the surface, respectively.

In practice, felületbe appears in contexts such as construction, materials science, or geology, where it is important to specify that a process acts into the surface. Example: A fúró a felületbe hatolt. (The drill penetrated into the surface.) The term is primarily a grammatical tool rather than a standalone concept, and its use depends on the surrounding verb and the intended direction of motion.

Related concepts include the base noun felület (surface) and other illative forms for different nouns. Understanding felületbe requires basic knowledge of Hungarian case endings and their role in indicating spatial direction.
