oikeakätisestä

Oikeakätisestä is the elative singular form of the Finnish adjective oikeakätinen, which means right-handed. The base adjective describes a person who predominantly uses the right hand for tasks such as writing, throwing, or manipulating objects. In Finnish, oikeakätinen has an antonym, vasenkätinen, meaning left-handed, and the noun for the trait is oikeakätisyys (right-handedness).

The word is used in everyday language to refer to individuals or to properties associated with right-handedness. As a grammatical form, oikeakätisestä appears in contexts that require the elative case, for example when saying “from/about a right-handed person.” The concept of handedness relates to the neurological and motor preferences that typically favor one side of the body; in humans, the majority are right-handed, while a minority are left-handed or ambidextrous. In practical terms, oikeakätinen is used in science, ergonomics, sports, and design when describing equipment, environments, or people that favor the right hand.

Etymologically, oikeakätinen is a compound of oikea (right, correct) and käsi (hand) with the adjectival suffix -inen. The term reflects the common Finnish method of forming descriptions of physical or behavioral traits by combining core words with -inen.
