nehladký

Nehladký is an adjective used in Czech and Slovak to describe a surface, material, or texture that is not smooth; it denotes roughness or irregularities in texture, in contrast with hladký (smooth). It can apply to metal, wood, stone surfaces, fabrics, or skin when rough to touch. The term is common in technical, descriptive, or scientific writing as well as in general descriptions.

Origin and form: The word is formed with the negative prefix ne- attached to the adjective hladký (smooth). It inflects like other adjectives and agrees with the noun in gender, number, and case (for example nehladký povrch for a masculine singular noun, nehladká textúra for a feminine singular noun).

Usage: In everyday speech, speakers may opt for synonyms such as drsný (rough) or nerovný (uneven) depending on nuance. Nehladký emphasizes a perceptible roughness or irregular texture rather than merely the absence of polish. It is common in engineering, construction, material science, design, or dermatology when describing surfaces or tactile qualities.
