Tehokkaan

Tehokkaan is the genitive singular form of the Finnish adjective tehokas, meaning effective or efficient. In Finnish, adjectives inflect to agree with the noun they modify in case and number, so tehokkaan is used when the noun it describes is in the genitive singular. The base form tehokas is used in dictionaries and when the noun is in other cases.

Tehokkaan commonly appears in phrases where the noun it modifies is in genitive, for example: “tehokkaan laitteen hinta” (the price of the efficient device) or “tehokkaan työn tulos” (the result of efficient work). These constructions show how the adjective marks the quality of the head noun within a genitive noun phrase.

It is widely used in everyday language as well as business, technology, and media to describe methods, tools, processes, or strategies that deliver desirable outcomes with relative ease or resource efficiency.

Etymology and related terms: tehokas is derived from teho, meaning power or effect, with a productive suffix forming an adjective. Related Finnish terms include tehokkuus (efficiency), teho (power, effect), and tuotantotehokkuus (production efficiency).
