wydajny

Wydajny is a Polish adjective that denotes efficiency or high output. It describes objects, systems, or processes that deliver considerable results while using relatively few resources or time.

Commonly applied to technology and machinery, for example: wydajny procesor, wydajny silnik, and wydajny system chłodzenia. The feminine form is used with feminine nouns, such as wydajna bateria. The related noun is wydajność, meaning efficiency or output.

Grammatical forms include the masculine singular wydajny, the feminine singular wydajna, and the neuter singular wydajne; plural forms are wydajni (masculine personal) and wydajne (other plural). These forms allow the word to agree with the noun it modifies.

Etymology and semantics: the adjective is linked to the root wydaj-, which appears in the noun wydajność and derives from the verb wydawać, meaning to yield or to deliver. The term conveys a sense of performance optimized to produce results, often with an emphasis on resource efficiency.

Usage notes: wydajny is commonly used for hardware and processes, such as computers, engines, or workflows, where high performance and low waste are valued. It is closely related to, but not always interchangeable with, synonyms like efektywny (efficient) and wydolny (capable of functioning under load). In everyday language, it typically describes technical or systematic performance rather than people.
