läpäisi

läpäisi is the past tense, indicative mood, third‑person singular form of the Finnish verb läpäistä. The verb läpäistä has two main senses: (1) to pass through a physical space, as in “läpäisti harjan” (passed through the fence); and (2) to pass a test, exam, or other assessment, as in “läpäisti kokeen” (passed the exam). The verb is transitive and often requires a direct object, though it can be used with an infinitive construction: “läpäisiin? läpäiskö?” in dialectal speech.

In standard Finnish, the infinitive is läpäistä, the present participle is läpäisevä, and the past participle is läpäistä. The form läpäisi is used in narratives describing actions that have already happened. Example usage: “Koululainen läpäisi oppaansa luokan päätehi ratkaisemalla salaisuuden” illustrating a typical sentence in Finnish literature.

Morphologically, the word is built from the stem läpäis- plus the past tense suffix –i. It follows the regular conjugation pattern for short‑vowel verbs. The word is common in colloquial speech and writing, especially in contexts where verbs of passing or succeeding are employed. Its antonymic counterpart, epäonnistui (failed), is often paired in comparative contexts.

Because of its generic nature, läpäisi appears in a variety of idioms and compound terms, such as läpäisyhinta (passing price) in economics or kalja-läpäisy (a type of drinking game in which participants must pass a drink). The term is widely understood by speakers of Finnish and appears regularly in media, educational contexts, and everyday conversation.
