Tehokkuudeltaan

Tehokkuudeltaan is a Finnish expression used to indicate “in terms of efficiency” or “efficiency-wise.” It is formed from the noun tehokkuus (efficiency, effectiveness) with the suffix -deltaan, which signals that the statement concerns a specific dimension or aspect. The construction is common in formal and technical Finnish when comparing items along one criterion.

Usage and meaning: The function of effektivities like tehokkuudeltaan is to frame a comparison so that the evaluated attribute is explicitly stated. Common patterns include attributive phrases such as tehokkuudeltaan parempi or tehokkuudeltaan heikompi, meaning “more efficient” or “less efficient” respectively. The form often appears in sentences that compare two or more alternatives, systems, or products. For example: “Ratkaisu A on tehokkuudeltaan parempi kuin ratkaisu B.” or “Energiankulutuksen suhteen laite X on tehokkuudeltaan parempi kuin laite Y.”

Related usage: The same productive pattern can be used with other nouns to express different dimensions, such as kestävyy­deltään (in terms of durability) or turvallisuudeltaan (in terms of safety). This makes the suffix a common tool for concise dimensional comparisons in Finnish, particularly in reports, analyses, and technical writing.

Etymology and register: The form combines tehokkuus with the dimension-marking suffix -deltaan, aligning with Finnish practices of appending -deltaan to refer to a particular aspect. It is widely understood and accepted in standard Finnish, though its use may feel more technical or formal depending on context. It is less common in casual speech, where simpler phrasing is often chosen.

In short, tehokkuudeltaan is a concise, widely used way to specify that a statement relates to efficiency as the point of comparison.
