Efektivní

Efektivní is a Czech adjective meaning "effective" or "efficient." It describes actions, processes, or results that achieve desired outcomes with optimal use of resources. The word derives from the noun efekt and from efektivita (effectiveness), formed with the suffix -ní to make an adjective.

In usage, efektivní is common in business, administration, science, education, and everyday speech. It often connotes practical productivity and resource efficiency, though it can also mean simply that something works as intended. It is distinguished from the closely related term účinný, which stresses the ability to produce the desired result, sometimes irrespective of resource use. The noun forms efektivita (the state or degree of efficiency or effectiveness) and účinnost (the act of achieving an effect or potency) are used in formal writing and statistics.

Typical phrases include efektivní řešení (an effective/efficient solution), efektivní řízení nákladů (cost-efficient management), efektivní algoritmus (efficient algorithm), and efektivní výuka (effective teaching). The term is applied across sectors, including public policy, healthcare, and industry.

Grammatically, efektivní declines with gender and number like other Czech adjectives; the form shown here is the masculine singular nominative.
