läpikäyneet

Läpikäyneet is a Finnish word that functions as a plural past participle, formed from the verb läpäistä and used as an adjective or as a nominal phrase. The term literally conveys that something has been gone through or experienced, often referring to processes, events, or sets of experiences that have been completed or traversed.

In use, läpikäyneet describes nouns that have undergone a sequence or evaluation. It commonly appears in contexts such as reports, procedures, and descriptions where it is important to indicate that certain steps, tests, or experiences have already occurred. For example, läpikäyneet vaiheet refers to the stages that have already been completed, and läpikäyneet asiakkaat can be used to describe customers who have gone through a particular process. The form agrees in number with the noun it modifies (singular: läpikäynyt; plural: läpikäyneet).

Läpikäyneet can also function as a substantive phrase referring to people or things that have experienced or endured something, though its primary usage remains descriptive rather than as a fixed noun. It is linked to related participial forms such as läpikäynyt (singular) and läpikäyneet (plural) and is part of Finnish participial morphology that allows adjectives to carry temporal and experiential information.

Etymologically, the word blends the verb läpäistä (to pass through, to complete) with the common participial suffix -nyt, yielding a plural form that signals completed passage or experience.
