käytto

Käyttö is a Finnish noun meaning use, utilization, or usage. The standard spelling includes the letters ä and ö, and the non-diacritic form kaytto or kaytto is sometimes seen in contexts where diacritics are not available; however, the normative Finnish form is käytto? No—the normative is käyttö, with ä and ö. The word is derived from the verb käyttää, meaning to use, with a common noun-forming suffix.

In everyday language, käyttö refers to the act of using something: for example, a device’s käyttö or a procedure’s use. It also denotes the way something is used or its function, that is, its intended purpose or application. In statistics and planning, käyttö can describe how much something is used or consumed, often expressed via related terms like käyttöaste (utilization rate) or kulutuskäyttö (level of consumption). In linguistic or cultural contexts, kielenkäyttö means language use, illustrating the broader semantic field of活動.

Käyttö appears in many compound words that specify aspects of use: käyttötarkoitus (intended use), käyttöohje (instruction for use), käyttöaika (amount of time something is in use), and käyttöoikeus (right to use, license). The form myös appears in phrases such as käytössä (in use) and käyttöön (for use). In technology, käyttöjärjestelmä (operating system) and käyttöliittymä (user interface) are common examples of extended uses of the concept.

Grammatically, käyttö is a neuter noun. The genitive singular is käytön; the partitive singular is käyttöä; the plural nominative is käyttöjä, with corresponding plurals in other cases as appropriate. Overall, käyttö is a central Finnish concept spanning everyday usage, technical terminology, and legal contexts.
