läpäistään

Läpäistään is the present passive form of the Finnish verb läpäistä, meaning to pass through, permeate, or, in the context of examinations, to pass. In the passive voice, the performer of the action is not specified, and the subject is the thing that is affected. The form is used across formal, scientific, and descriptive contexts.

In usage, läpäistään describes both physical permeation and abstract success. For example, in a physical sense one might say that water percolates or permeates a material, expressed as the material läpäistään vedellä (the material is permeated by water). In education or testing, it can express that an exam is passed, as in Koe läpäistään helposti (The test is passed easily). The construction is impersonal and does not name an agent.

Morphology and spelling: läpäistään is a present tense passive form built from the stem läpäis- plus the suffix -tään. It is the same form for all subjects and persons, reflecting Finnish passive grammar where the agent is often unspecified or stated with an instrumental phrase.

Related terms: läpäisy refers to permeation or permeability, and läpäisevä means permeable. These derivatives are common in technical, scientific, and everyday language to describe how substances or signals pass through barriers or media.
