vadné

Vadné is a Czech adjective meaning defective, faulty, or impaired. It is derived from the noun vada, which denotes a defect or fault. The term is commonly used to describe goods, components, or processes that do not meet required standards or expectations.

Grammatical usage is as an attributive adjective that agrees with the noun it modifies. For example, masculine singular: vadný výrobek (a defective product); feminine singular: vadná součástka (a defective component); neuter singular: vadné zboží (defective goods). Plural forms vary with the noun, but the key idea remains that vadné signals an imperfection relative to a normative standard.

In everyday and professional language, vadné appears in contexts such as manufacturing, quality control, retail, and consumer protection. Common phrases include vadné zboží (defective goods), vadný výrobek (defective product), and the related verb phrase odstranit vadu (to fix or remove a defect). The term is also used in discussions of warranty and liability for defects.

Etymologically, vadné is linked to vada, and both are part of a family of words describing flaws. Related terms include vady (defects) in the plural and závada (fault or malfunction) with a somewhat broader sense of failure or interruption. While vadné focuses on imperfection in an object, závada often emphasizes a specific malfunction or obstruction.
