käyttetty

Käyttetty is a form associated with the Finnish verb käyttää, meaning to use. In standard Finnish, the past participle that expresses “used” or “utilized” is kirjoitettu ja säädetty as "käytetty." The form "käyttetty" with two consecutive t-tä (double t) is generally considered a misspelling or nonstandard variant rather than a correct inflection. Despite this, readers may encounter "käyttetty" in informal writing or typographical errors.

Grammatically, käytetty functions as a past passive participle and can act as an adjective or part of a compound verbal construction. It agrees with the noun it modifies in number and case, for example: käytetty auto (a used car), käytetyt tuotteet (used products), käytettyjen autojen hinnat (prices of used cars). The correct stem formation comes from käyttää -> käyt-, and the participle suffix -etty yields käytetty.

In usage, käytetty is common in everyday Finnish, particularly in contexts such as commerce, classifieds, and descriptions of products or equipment. The word conveys that an item has already undergone use, and it does not denote the act of using itself, but the state of having been used.

See also: käytä (to use), käytöstä (from use, usage), käytettyjen tuotteiden myynti (sale of used goods).

Note: When writing formally or publishing in Finnish, prefer käytetty over käytettyytta variants; avoid "käyttetty" to maintain orthographic correctness. If confronted with the form "käyttetty" in text, consider it a probable typographical error and correct it to "käytetty."
